Re: [DML] Back on track! (update)

Well thanks to Nick Pittelo (sp?) he helped me track down why my 
frequency valve was not working....there was a ground connection that 
was not connected. After bolting it down to a good ground source it 
started to buzz away! The ground connection is the single black wire 
that comes out of the engine harness approximatley midway in the 
engine compartment (behind the fuel distributor area) It has a Lug 
crimped on the end of it for a bolt with some red tubing extending 
out from the lug...it also has a single male/female connector near 
the lug so that you can disconnect the ground for the Frequency 
Valve?...I guess for disconeccting it quickly for some reason?

I still have a slight backfiring froblem in the high RPMs when I rev 
the engine and occasianally in the lows. Could the Warm Up Regulator 
be causing this? I opened it up and the wires were fried in it but 
the resistor inside it (wrapped around the bi-metal strip) was good. 
I tried re-wiring it with some High Heat Teflon coated wiring to see 
if it would work. I'm still working on that problem and will keep you 
guys updated in case anyone else runs into the same problem. I have 
to run more tests on the Warm Up Regulator.
