rustydog Posted October 19, 2013 Share Posted October 19, 2013 HAVE CONVERTED B MODEL TO 12V NEG GRND. WIRING THE AMMETER GUAGE.....DOES THE NEG SIDE GO TO VOLTAGE REG?? I HAVE THE POS SIDE OF AMMETER WIRED TO LIGHT SWITCH, ETC. IS THIS CORRECT OR REVERSED??? THANKS FOR THE HELP Quote Link to comment https://www.bigmacktrucks.com/topic/33187-another-electrical-question/ Share on other sites More sharing options...
leversole Posted October 19, 2013 Share Posted October 19, 2013 Negative comes from voltage regualtor and goes to light switch, postive goes to terminal black on firewall and eventually back to battery cable...you are measureing everything coming and going to the battery Quote Link to comment https://www.bigmacktrucks.com/topic/33187-another-electrical-question/#findComment-212354 Share on other sites More sharing options...

NEG SIDE OF GAGE ONE WIRE TO VOLT REG TERM-BAT. AND OTHER ONE ON THERE TO LIGHT SW. RIGHT??

leversole Posted October 20, 2013 Share Posted October 20, 2013 That's right...you know there is a B-61 wiring diagram on this site in the wiki...very helpful...

rustydog Posted October 20, 2013 Author Share Posted October 20, 2013 That's right...you know there is a B-61 wiring diagram on this site in the wiki...very helpful...Les,....dont know if you'll see this today, but, yes I have blown up copies of two diagrams that I used to rewire and make whole new "harness". Problem is that I don't really know electric theory, so some things I just dont understand. I wired it the way you said, and ammeter and fuel gage dont work. Had a friend helping me and we installed a master cutoff switch, which shorted out when the connector on one cable hit the body of switch. (this was last week) lights work, heater works. Is it possible the two electric gages were burnt out by that short?? I fired her up today and polarized the volt reg/generator. how /where do I test it to see if its puttin out?? thanks, Rusty Quote Link to comment https://www.bigmacktrucks.com/topic/33187-another-electrical-question/#findComment-212521 Share on other sites More sharing options...
leversole Posted October 20, 2013 Share Posted October 20, 2013 Check the battery voltage with the engine off, then check with engine ruinning, if generator is putting out, voltage will be higher with engine running...actual numebrs depend on a lot of variables....

thomastractorsvc Posted November 14, 2013 Share Posted November 14, 2013 Just put a 12v DELCO style alternator on it and take that old stuff off, you will be way head. The alternator should bolt right up use the generator pulley sheave. There is a couple of threads on here about the alternator swaps. Quote Robert"I reject your reality and substitute my own."

Mike Posted November 18, 2013 Share Posted November 18, 2013 I second the motion. It makes things more simple and you can rest nights. But if you cannot it is understandable that costs can be high when changing out most things. Like new cables, alternator, starter, etc. etc.mike Quote Link to comment https://www.bigmacktrucks.com/topic/33187-another-electrical-question/#findComment-217315 Share on other sites More sharing options...
