Aftermarket radios can be a battery killer.
Starters don't have trickle drain problem. Alternators do.
Easy to figure out. Get a inline amp meter and monitor the current draw with all hooked up. Do not try to start car or run anything other than have door open. You can blow the meter. Then unhook the alternator, see if drain goes away.
"If you do change the starter. I always recommend stepping up to a newer GM PMGR (permanent magnet gear reduction) unit.
For the 153 tooth flywheels , I believe it is a 1995 Camaro with 305 starter
For 168 tooth use a 1996 Silverado with 350 starter.
They are a direct bolt in, are high torq and low weight.
Some older engines (pre 74?) will only be drilled for 2 straight across starter bolts, these require the diagonal bolt. It will need to be drilled and tapped. Easy to do."
Tom do you have a part number for the starter you recommend?
