I have had the "hot starts need boost switch" problem for osme time and knew I needed to do something about it.
I have reviewed http://www.gmcmotorhome.info/chassis.html#GROUND
but am confused.
This paragraph is throwing me:
--------
There should be a large battery cable from the engine battery directly to the starter and then to the chassis. The Engine with the Alternator (the source) and Starter(the load), is the MOTHER of all grounds. All grounds including the Batteries should return to this point. Some owners buy Engine Batteries with side and top terminals so there is a convenient place for this cable. This cable will normally fix the infamous "hot Starter " and "only starts with the Boost Switch" problems. There have been reports of the starting current melting the Oil Dipstick and electrical arcing through the bearings in the transmission.
------------
Right now I have one cable going from the negative terminal of the engine battery to a point on the engine block. when the text says I need a cable from the engine battery to the starter and then to the chassis. I am not sure what I need to add.
Is there already some point on the chassis to connect this to? If not does that mean drilling a hole in the frame, or attaching it to the aluminum body? In either case where should I do that?
I have not really looked at or for the starter, but is there a ground connection lug on it somewhere already? If not how do I get a ground cable attached to the starter?
Some pictures would be great.
