Re: {Chrysler 300} c300 electrical issues

Remember , battery is about 80 -90 AH , it takes three hours at 35 A to refill . Starter takes 200-300 out . 10- 20 minutes cranking wipes out battery . A lot of cranking energy has to be replaced before you see 14 v
So system may innfact be fine ? put on charger ( 15 A , overnight , ? 100 AH in , ) see what happens ..

Charging Voltage is low enough to prevent proper charge of the battery—or just dying off under excessive load. Should be 14.5-15.0 Volts. See: electrical.pdf (jholst.net) Page 92 Sounds more and more like the Voltage regulator.

I should have added that in spite of the high rate of charge the voltage is still 13v

Hi everyone,

Just when I thought I was done with the restoration in time drive it before the snow flies ---

It ran great on 3 short drives, then it started running progressively worse until it quit altogether. There was probably less than 1 hour total run time on the restoration.

The whole time it was running around the neighborhood I noticed that the ammeter was pegged on the high side. I could turn on all the accessories and get it down about half charge. We rolled up our sleeves. BTW, the car was converted to 1956 = 12 v components in the late 60’s

We eliminated fuel as the problem but we did find some ignition gremlins. Coil was switched, no change, ballast resistor and other components switched out and it still would not start or run. Then we put in a complete junk yard distributor in and it started right up, idled and ran great. Today I changed the condenser in the rebuilt 1^st distributor and put it back in. It still starts, idles and runs great.

The very high rate of charge is still there – is this a problem? Could it have contributed to the condenser failure? Is there anything else I need to investigate?

Thanks as always

…Jack
