I checked the current draw this morning.
Without radio draw is about 5 mA
With radio its about 200mA

New battery has been cranking fine all weekend, no sign of weakness with all the Weekend start and stops and short trips. So Im optimistic alternator and battery are OK.

I have been using my digital meter, and for comparison connected my old Simpson analog. The analog read the same, but interesting, it captures current surges from the clock. Every 1 (ONE) second, the needle surges one milliamp or so. I would think this is the mechanism ticking away, and the each second there is a small surge in current.

My Digital meter doesn't seem to capture the surge, it must filter it out?

Thanks for all the input, I think the short in the radio, caused a higher draw, which may have contributed to shortening the battery life. Over 2 days, 200mA, can add up two almost 10 amp hours of drain on the battery.

I went straight for the after market radio as the suspect from reading the FAQ and other posts on battery drain. Tin whiskers in the radio causing a short somewhere.
