electrical trouble

I have an 84 Bronco w/302. It has an electrical drain and will kill the battery in a day or two if it isn't run. I had the battery charger on it when I fired it up and was revving it. The dome light blew as the engine died. The fusable link running from the solonoid to the alternator also went. I replaced the link. but two wires from the link run to the module on the fender nect to the solonoid. I think it's the voltage regulator. Anyone know where I should start replacing modules? Could I have toasted the coil, ignition module, etc.? Any help is greatly appreciated.

why would you start replacing modules if you already thing its the regulator? start there, as that sounds like its shot to begin with. Then charge it (might need a new battery after overcharging) and go from there.

I didn't know if it was the regulator or not. I replaced the regulator and it hasn't fixed the problem. I was trying to find out what order to check things in and what parts are more likely to fail with an over charge. Any help would be great.

Does the regulator have a good ground? I replaced mine on saturday, and I didnt mount it at first and my voltage was about 16-18, and I shut it right off and bolted it down, broght it right down to 14

The sheet metal was clean, except for the paint, so I think it should be good. Is it possible for the solonoid to have fried? Just graping at straws here...when it comes to electrical I am lost. Thanks for the help, please keep it coming!!

I had this happen to me on a ford truck I had in the past and it had a bad engine to body ground strap,might be worth a check.I was putting out almost 17 volts and started to boil my battery.

I'll give it a look. I think my trouble was leaving the battery charger connected while running/revving the engine. Did you have any trouble from running 17 volts?

Examples of circuits where the Fusible Link wire will be the most reliable short-circuit protection are; *the main power wire to the dash area, *the alternator-to-battery “charging wire,” *power-up wire to electric radiator fans, and other systems where the amount of current flow is a large amount for long periods of time.

NOTES about Fusible Links Only a serious short will cause a Fusible Link to burn–it disconnects a circuit from power just before the rest of the wiring in a circuit would be damaged. Momentary overloads will not burn out a Fusible Link–such as arcing a wrench between ground and an exposed terminal.

The insulation of the Fusible Link wire is soft and non-flammable, sometimes the conductor strands within will burn without noticeable damage to the insulation. A good test is to try stretching it. If it stretches like a rubber band then the wire within has burned out.
