Just beware, you may have multiple electrical problem. The good news, is it's still doing it so hopefully it's gone from intermittant to persistant. _Much_ easier to fix a persistant problem. I'll try jumping it first, just to rule that out. Next, I'll check the control wire to the solenoid (terminal #30), the Bentley manual says if I've got more than 8V there when the key is in the start position, the wiring and switch are good. So, from there, it's just a case of which side of the system the problem is on. If anything photographable goes on, I'll take and post pictures with descriptions. Dave Hinz
