I have a 66 Plymouth Belvedere II. with a MSD 6AL ignition. When the car is at idle the charging is ok, but once I touch the brake or turn the wipers or lights on my car starts to pull from the battery. The alternator is a 60 amp, I had it build up to a 100amp but that did not help, so I brought back down to 60. When I pulled the pcv valve out of the valve cover the charging seemed to get better, but it still discharges. Any suggestions that would be great

dcatcha,

your situation is normal. almost every vehicle is the same way; an engine cannot create enough power at idle to supply enough electrical power to run things. At idle speed the revs are too low to run the car so it gets its extra power from the battery. Don't worry about.

if this is more serious than it sounds,i would suggest you look at powermasters new alternators.they are made to put out more at idle and at running rpm`s.

Is your idle to low?

I agree with johnymorar. This is quite normal. The only time it would be concidered abnormal would be if the battery is actualy going flat. Under normal circumstances you should be charging at higher revs more than you sit at idle so in theory the battery should not go flat. If it does then you may have a problem, or you are spending prolonged periods at idle with accesories running.

Easy fix if you need more juice at idle (like for big stereos) put a smaller pulley on the alternator, she will put out more juice at idle using this method. Your problem is typical and normal.

every mopar i've ever driven has had a sensitive ampmeter. it's perfectly normal.
