Hi Phil
I really appreciate your comments & will check my selenoid contacts this morning
I did put a voltmeter on both sides of the selenoid & got the same reading on both sides:12.2 I understand from others if the reading on both sides is the same then devise is good I understand reading at selenoid should be same as converter output which is 13.7 Don't know where I'm losing the 1.5 difference????
Only 5 feet between converter & battery selenoid
Plan on crawling under MH to try & locate cable to see if damaged in any way
Does the engine power boast switch come into play here???
Not to smart when to comes to electricty but if conact on selenoid appear corroded if I turn off or disconnect all power sources including chassis battery can I safely work on selenoid????
Thanks
Ted
