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

George,
   4 ga wire is a bit small for a starter. I have 2 gu welding wire that
East Coast Scout Parts used to make. I guess they still do, haven't spoke to
them in a while. Really nice with crimped eyes on both ends. Starter really
spins with them on it.

  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.
