[COUPERS-TECH] Re: [COUPERS-FLYIN] master switch wire identification

----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]---- Stan:   It would appear to my eye that the wire to the field lead of the generator is shorted to ground.  The field is switched off ( open) at the same time as the master is switched off (open) to keep the generator from running as a motor if the current relay in the voltage regulator sticks, which it is wont to do.  I think the generator field leads are shielded cables, check for a short to the shield.   Wayne Woollard ----- Original Message ----- From: Stan To: flyin@ercoupers.com ; tech@ercoupers.com Sent: Wednesday, April 02, 2003 4:01 PM Subject: Re: [COUPERS-FLYIN] master switch wire identification ----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]---- Ok, I'm all cornfused now. The switch on the panel cuts off power to the "arm" lead on the voltage regulator- I know that. It doesn't appear that the switch on the master (in luggage compartment) cuts out the field though since it is always grounded no matter what position the switch is in. I would imagine that if it cut the ground to the field then it would be ungrounded when the swith was off, right??   In any event I still can't figure out why my generator isn't charging. 1. Generator works off the plane 2) field has been flashed correctly (gen works off plane) 3. voltage regulator works off the plane according to the shop I took it in to   What else to check? This thing is driving me crazy!   Thanks. Stan   +++++++++++++++++++++++++++++ that other wire is your generator field wire. Sounds like you now have 2 generator switches- the question is are they both wired to the generator field?? ++++++++++++++++++++++++++++ These wires cut off the generators F-lead which goes to the regulator. So it's basically taking the sources of electricity off when you take out the master ( this is handy in cases of electrical fires and the like ) Do you Yahoo!? Yahoo!
