Trip Update

Dead in the Water
and only
250 Miles From Home

We Have Had An Excellent 5 Week Trip
Leaving Alabama Up Thru The Northeast
Tip of Georgia And Thru The Mountians
Of Tennessee, Virginia & West Virginia.

Traveling On Thru Pennsylvania, New York,
Ontario, Michigan And Spent A Couple Of
Weeks In South Bend Indiana Visiting And
Doing Chores For My 98 Year Old Mother.

Leaving South Bend We Meandered Down Thru
Illinois And Detoured Over To Eat At That
'THROWED ROLL Place ' In Sikeston Missouri.
Leaving There We Traveled Across Western
Kentucky With Out Problems.

We Used The Barbarian Each Night, We Used
The Trusty Old Furnance { except while in
South Bend } And It Worked Flawless.
The Ole '78 Ran Well, Got Good Fuel Mileage
and Only 250 Milers From Home
We Are Dead In The Water ~

Soon After Entering West Tennessee
{during heavy Rain }
I Noticed The Red Alternator Light And I
Pulled To Check The Belts ~ They Were OK ~
While The Motor Was Running I Disconected
The Positive Battery Cable And The Engine
Kept On Running So I assumed The Alternator
Was Charging. I Turned On The Headlights
Without Any Problems.

As We Were Continuing On To The Next Exit
The Engine Backfired And Died While Rolling
I Quickly Fired Up The Onan,
Got The Engine Started
And Made It Off The Exit ~
It Drained The Batteries

Disconnected The TOAD, Charged Up The House
Batteries, Charged Up The Coach Battery And
The Ole '78 Starts And Runs Good
UNTIL
You Turn On The Lights
Or Anything Else That Draws Power ~

Before The Trip We Installed The Following;
New Alternator
New Battery
New Belts
New Battery Combiner
New Battery Isolator
New Battery Boost Solonoid
New Head Lights
New LED Tail Lights
New LED Park Lights
New LED Marker Lights

ANY SUGGESTIONS ? ? ?

The source of power for everything is the alternator. The battery(s) is just a storage device. Fire up the coach and go to the isolator center terminal Read the voltage from there to the aluminum plate that the isolator is mounted on. If it is around 14.7 volts read the voltage at the top and bottom terminal of the isolator. They should be around 14 volts.

If the center terminal voltage is wrong fix the alternator. If the top or bottom terminal voltage is bad replace the isolator.

Sounds to me like your alternator took a crap. When I purchased our coach in
2006 and started driving back to Wisconsin from Charleston, SC. All was well
until I turned on the lights......DONE !

Called a service company and they came and charged the battery and told me where
to go in the morning. Got to the auto electric place......they rebuilt the
alternator on the spot, problem solved.

I'll guess the NEW Alternator was a REBUILT? If so that is more likely the fail mode. Hope your are all sorted soon.

Just got the wife home in the toad
late last night and I Slept Til 10 AM

I plan to go back tomorrow for the GMC

Joe,

I've been led to believe that you can run your Onan, jumper the boost soleniod, and run your ignition (and chassis electrical system) off the battery charger. It might work to get the coach back home where you can work on it at your leisure.

It does sound like the alternator died on you. It's possible the chassis battery developed a sudden dead short as well, but I'm not sure it would present the same symptoms.

I think if the HEI module was gone it wouldn't start at all.

Joe, perhaps all of that electrical work you did before you started your
trip has some bearing on your present problem. I would look carefully at
all connections. Incidentally I would not be too hasty when it comes to
removing battery cables with the engine running. Alternators are proven to
NOT LIKE THAT very much, to say nothing of isolators. That being said,
check the state of charge on the engine battery. A fully charged lead acid
wet cell could ideally have a voltage potential at 70 degrees of 2.2 volts
per cell times 6 cells = 13.2 volts. If your house battery is 12.4 or 5 it
is fairly well discharged. That, combined with the load from the
headlights would drop your voltage below the point where the ignition coil
would cease to work. You should be able to run the Onan, jumper the
isolator from the house battery to the engine battery, and drive it home
with the Onan running. Then fix it at home at your leisure. JWIWD.

That's what you get for not calling me to eat at Lambert's with you. Fire up the Onan and head on back to Alabama. You can fix it in your driveway then.

Yes, you can do that -- however that does still leave the house battery in the circuit.

One should NEVER run the engine off the alternator with the battery disconnected. The battery serves as a "buffer" against the alternator putting out higher voltage power surges. Those can ruin a lot of electrical parts such as the coil, module, etc. I knew someone that did this once and it burned out his headlights, dash bulbs and other exterior lights as well as ruining most of his ignition parts.

I should have added one more step to this. If all of the above three voltages read correct, turn on the headlights and read them again. They should read similar numbers or slightly lower.

A momentary disconnect from the battery to verify that the engine continued to run rarely caused any problems in 70's vehicles (with their points/condenser ignitions) and was a standard practice of shade-tree mechanics. Newer electronic ignitions might be less robust.
How long did it take to burn out the headlights, dash bulbs, and iginition?

I'm wondering why it died so quick if the light just came on shortly before it died. Could it be a shorted engine battery? In my experience, a strong battery will run for quite a while before it leave you dead. I drove a 73 Imperial with the AC on for over 100 miles.

I believe that dying/dead (but not shorted) batteries can show
what's called a surface charge while the generator is supplying
a proper charging voltage. However, as soon as the charging
voltge disappears, that surface charge drops to almost nothing.
The battery has no capacity to supply current any more.

If the voltages stated by Ken Burton are correct, it's time for
your battery to be used for the "core charge" toward a new one!

He obviously had a bad alternator that was putting out too high a voltage. That is what ruined his battery and when he unhooked his battery while the engine was running the high voltage burned out his light bulbs and other things within a minute.

The battery >may< not be that strong... and it may have been discharging a small amount all along.  Which is why I have ammeters (2) in my coach.  Incidentally, the ignition system on that Imperial was probably the most efficient electronic system ever made, and arguably the most reliable.

If it was the same system used by Plymouth at that time I would argue the reliable comment. If you carried a spare resistor and knew how to change it, then yes, it was reliable. Certainly more reliable than the normal points/condenser system in general use at the time.

I'm wondering why it died so quick if the light just came on shortly before it died. Could it be a shorted engine battery? In my experience, a strong battery will run for quite a while before it leave you dead. I drove a 73 Imperial with the AC on for over 100 miles.


I can tell you at a certain low enough voltage the HEI will just stop working unlike a points setup that just keeps lowering the voltage to the plugs till it stops.

This is an interesting call, could be ! Had it happen to a fairly new Harley
Battery. Everything was perfect, shut the bike off....battery was instantly
dead as can be. It would take a surface charge until I tried to start the bike,
bang, instantly dead.

He obviously had a bad alternator that was putting out too high a voltage. That is what ruined his battery and when he unhooked his battery while the engine was running the high voltage burned out his light bulbs and other things within a minute.



Emery Stora








Yep, what Emery said. Had a new alternator lose it's regulator and the voltage meter jumped up to about 17 volts. I was just arriving at Blaine's. Pulled the headlights on to get the voltage down til I could shut it off in his driveway. Alternator had 3,000 miles on it from Fremont, Ca. Took 3 from Autozone to get a good one. Had one rebuilt locally and carry it as a spare now. Don't pull a lead from the battery with engine running, ever.
