Re: [ihc] Re: Humphrey's Coil Voltage

[George B Humphrey <xgbhx@xxxxxxxx>]

	You are probably right about this. I noticed a change in voltage draw,
after I installed the Ford solenoid. I've never changed the starter and
everything on the Scout was old or original when I bought it. How much
did your cheapo tester cost? Can auto parts stores do this test, without
removing the starter? I definitely will get it tested. Thank you for the
suggestion.
 
	I made the conversion because the 345 puts out a lot of heat when
crawling through the desert. I figured as a preventative measure, to keep
me from sitting in 100+ weather waiting for the starter solenoid to cool
down, I would do the conversion. 

	4 gauge wire all the way, battery to starter.
