[ausev] Troubleshooting electrical drain issues

[Mike Delany]

Ouch.   Burning through all 350W is not good.  How about switching to LED 
break lights if you really are getting that close.  Have you tried wiring 
in an old style automotive ammeter into the 12v circuit to see if you 
really are hitting 30 amps?
