electrical problem?

[eriemoto.]

i've recently been noticing some electrical problems with the cb. when i'm rolling up the windows, the engine RPM's will stumble slightly, and when i let go, it returns to normal. when i press the brakes at idle in park, it will also stumble, and regain itself when i release the brake. when it stumbles, all the lights dim slightly, but noticeably. should i start diagnosing with the battery?

id get a friend to help me and test with a multi meter while the car is running my guess is alternator but do your testing first

I was just about to say that...^^^you beat me to it HF22T....

yeah mayne, what he said ....test your alternator!

More than likely...its getting weak....the brush is probably getting worn down to the point where.....during additional load...its draining enough to where the engine RPM will drop a little or studder. so you might want to get a NEW or REBUILT alternator! NEW $200-$350....rebuilt $90-$175

either or..get another one!...have it tested under load!
