Trace charger [RE-wrenches]

[Chuck Heath, SunPower]

Tom Elliot asks...

No, its fueled by LPG (propane) and tied to Relay 7 on the Trace for 
automatic operation. It's been running automatically every 4-5 days for 
2-3 hours since the system was installed in February, 1998 with no 
problems except replacing a water pump on the Kohler.

Hopefully, I can borrow one from a broadcast engineering friend. I think 
you're on to something here. I just hope Trace will fix the problem.
