Certainly sounds like the power supply within your WTEC controller is failing.. Call John at Transmission Instruments

Hey thanks for the advice. I overnighted my ecu to John. Wouldn't have been able to figure it out without you guys. Thanks again!

Please let us know the details when you're running again. Mine is about the same age and I'd like to be prepared. Thanks, HarveyP

I had the same problem a couple of yrs ago.. turns out there is a power supply within the WTEC controller that, of course after only 20 yrs goes bad! (sarcasm) hehe. John's a good guy, very reasonable and very good at what he does.
