Hi all,
I have a 75 Glenbrook.
I was coming home yesterday from a short trip. At around the same time,
maybe the exact same time, I am not really sure, the GEN dash light came on
and I lost all the 12v on the house side. Checking the engine side voltage
with engine running, I am not getting the 14v I should. Engine side
voltage was only 12v so it seems the alternator is fried. The alternator
is 2-3 years old.
I have a PDI DC converter and the green light was not on the controller and
no voltage at the outputs. Unplugging it then plugging it back in caused a
click in the generator compartment vicinity.
Coach side batteries are two 6v golf cart batteries about 5 years old.
They are weak but holding a charge at 6v each. The cells were nearly dry.
I added 16 oz distilled water to each of them.
The generator will fire up off the house batteries.
I am not sure where to look next. My suspicion is the boost solenoid, I
believe it is called, in the generator compartment. There are two wires at
the top of the solenoid. One goes up the side towards the taillight and
one goes to a place I cannot quite remember right now. But with these
connected, when I connect the positive to the house battery I get one heck
of an arch off the battery terminal. Like a dead short is going on.
I did not get any voltage reading on the top connector of the solenoid nor
on the small wire on the side when I pressed the battery boost gauge on the
dash.
I found some info on the electrical and the solenoid but nothing real
specific and nothing in the shop manual. Is there any good documentation
on what all the wires do?
Any ideas what might be going on?
Thanks,
Alan LaVoisne
