A diode could be leaky, but I'm sure you know that. The only other comment I'll make is that it sounds like you've got an intermittent short circuit somewhere, but I'm sure you've suspected that too. No, there is one more comment. Maybe "Pappy" isn't telling you everything. Maybe he's run that "new" battery down dead a few times already and it just isn't holding a good charge anymore. Could that be possible? Maybe you're chasing an intermittent short circuit that just ain't there. --- QScan/PCB v1.19b / 01-0232 * Origin: IBMNet Connection - Indpls, IN - 317-882-5575 28.8 USR (1:231/1) --------------- FIDO MESSAGE AREA==> TOPIC: 246 AUTOMOTIVE Ref: F1100042 Date: 12/31/97 From: ROY J.

The Superbird was a Plymouth, although it is possible that a couple were re-skinned Dodges. If you're interested go to http://www.superbird.com there are some interesting links. The "winged" cars were effectively banned from NASCAR competition in 1972, they were too quick for their own good. cbowman@sinfo.net --- * Origin: Techshop's Southern Most Point - Panama (1:3651/9.10) --------------- FIDO MESSAGE AREA==> TOPIC: 246 AUTOMOTIVE Ref: F1100048 Date: 12/30/97 From: MARC GERGES Time: 11:31pm \/To: JASON WEDEHASE (Read 0 times) Subj: Forced Induction Salut Jason!
