Hi all - just replaced the alternator for the 2nd time in 2 years, with a continuing "problem" that I guess needs to be addressed: my coach starts and runs well enough, but the voltmeter reads under 12 volts on startup, and needs the engine to rev up before the volts jump up to around 14. Once it jumps up it stays there, until the next start of course.
Cannot find a specific reference to this in prior posts, but now I know lots about the nichrome resistance wire problem and the need for APC (I'll be in contact, Mr. Fisher, and I will be in Yachats mid August).
So any help advice is welcome.
OBTW, I do have some other electrical issues, mostly around gauges fluctuating with electricity, as in the gas gauge goes down when I touch the brakes or turn on the lights, and goes up when accelerating, but I assume there is short or shorts elsewhere that are unrelated to the startup voltage thing. Just mentioning here in case there is some possible connection. More on the shorting stuff later...
