[QUOTE=jamesham;27424]On my 96 Gulf Stream motorhome the house battery is on the passenger side by the door, but the "charging" solenoid is mounted on the outside wall of the first basement storage compartment on the driver's side. Took a lot of wire tracing to find it....just follow the large 4 gauge battery cables. The ignition switch "trigger" for the solenoid was a yellow wire clamped off the rear of the inside automotive fuse panel under the dash on the driver's side.
This position for the solenoid was kind of stupid thinking by Gulf Stream because it is exposed to all kinds of weather and out of sight for inspection. But it took 14 years for it to fail, so it must have been rugged.
Replaced with a standard 100amp 12 volt auto starter solenoid so hope for another 14 years of use.[QUOTE]
A starter solenoid is designed to be on for only a short time. The right solenoid for the job is one designed to be on for extended times. If you use the starter solenoid it will burn out. Look for one that is described 'continuous duty cycle'.
