Update: I replaced the generator

Hi, all,

Based on the comments above I did some checking and discovered the existing generator--a Delco model 1102715--was basically tired and not up to spec.

I ordered a rebuilt Delco generator and Delco voltage regulator from Tucson Packard (AKA Chirco). The generator was $185 with a $75 core charge. The voltage regulator was $85. Both items were somewhat disappointing. The pulley on the generator had a significant dent and the voltage regulator showed corrosion.

My mechanic was able to cannibalize the existing generator and swap the pulley. He installed the generator and lubricated the blower motor, too. He reported the existing voltage regulator was just fine, so he didn't use the new one.

I asked him to tune the charging system for the following condition: engine at idle, all running lights lit, (including headlights on 'high beam'), radio on, blower motor on and turn signal blinking.

The rebuilt generator is performing considerably better than the old one but there is still a significant battery drain when the above conditions are in effect and I pull away from a stop. My trouble is that I've installed a PerTronix electronic ignition. The car runs very well with that device but--and this is a big but--the ignition really sucks up the juice when I start moving. The ignition will cut out completely if the power drops below a certain level. This leaves me stopped in the middle of an intersection, frantically hitting the starter.

The solution, thus far, is to adjust the idle speed to where the amp meter shows minimal discharge when the car idles.

This is not the solution I prefer. The high idle burns a lot of gas and is also rather noisy.

So now I'm at a loss for the next step. Any suggestions?

Thanks much,

Mark
