I have a 79 bronco and im having a issue with the charging system. I was told that part of the charging system runs through the gauges, it that true? Because if so i dont have my gauges in and thats my issue
As far as I know, the only portion of the charging system that has anything to do with the gauge cluster is the charging indication(ammeter) which uses a pulsed 5 volt signal from the instrument control voltage regulator.
I would think having the gauge cluster pulled would not affect the charging system.
I agree with Doug....you might want to start with checking all connections from the battery, alternator and regulator.
Battery cables (as with others) can look good, but corrosion can creep up between the copper and insulation of the cable an create problems.
what gets me though is before i took out the gauges i never had a problem.... And now i have a new alt. and volt reg. but still not charging. I can put a jumper wire from the top wire on the volt reg.(green wire) to the pos. side of the battery and then it kicks the alt. on. but i have to do that every time i crank it.
Thats weird, but there has to be something there because on my 77 when i have a lot of electrical load on it (IE Fan, lights, etc) my gauges (all of them) read higher then normal....
My 83 used to do this same thing to....kinda nice turning your headlights on and gaining 1/4 tank of gas
