Charging system not working

I have a 74 Javelin that I rewired with an EZ Harness. I have everything working except the charging system. I wired the system leaving out the idiot light and replaced the Amp Meter with a voltage meter. I made the connections to the alternator per the instructions provided at the Painless website (EZ harness didn't provide instructions for an AMC). I replaced the alternator when I rebuilt the engine, as it was over 30 years old.

With the car running I get a voltage reading of 12.15 volts. I troubleshot everything and it appeared that the voltage regulator was bad. I purchased a new voltage regulator and installed it in the car. The charging system started putting out 13.75 volts with the car running. Things were fine for a few days but now the system has quit charging again. The voltage regulator was very warm to the touch and may have overheated thus destroyed. The regulator is electronic. Any ideas what could be causing me fry the regulator? Is there any way that a layman with a multi-meter can check the voltage regulator?

I searched Doc's stuff but couldn't find anything that helped.

Call up Painless Techline I'm sure that on the 4 pin connector, you have to have a 50-100 ohm resistor inline or a idiot light connected inline on the ( L ) terminal or the exact problem that your having will result, with a fried voltage regulator.

Hope this helps

Thanks for the reply. I was wondering if not having the bulb in the wiring might be a problem. I did some internet searching and found a diagram that should show me how to wire the bulb in properly. I hope this solves the problem.

I contacted Painless. An 82 ohm 5 watt resistor should correct the problem.

I soldered in the 82hom 5watt resistor and the charging system has sprang to life. Now I've noticed a brake line leak
