Dan n Friends Help me trouble shoot my DPR trouble shoot tool.

[sharpshooter33 at roadrunner.com (David Brown)]

OOOPS. I thought it was Voltage I was reading. I thought it was like an O2 
sensor for MS.

Ok so I have it assembled what am I looking at with mA's?  The DPR works on 
Amps? (pie on face)

I'll set it for mA's. 10mA to start with?  Then what am I looking for on 
diagnostics?

Thanks
David

Well, first off you should be measuring current through the circuit and 
setting it for 10 +/- 1 ma.
Also it's important that you maintain polarity with the maintenance harness 
in place. If you should reverse the wires then the engine won't run well if 
at all.
It may be simply that if you're measuring voltage the high impedance of the 
voltmeter is enough to impede the correct current flow through the DPR.

Ok I assembled the DPR/Multi meter tool pretty sure I got them wired right.

Plugged it in and it starts, but then won't maintain idle. The multimeter 
shows around 7.9v it doesn't change it just drops off even if you try to hit 
the pedal. the voltage remains around 7.9v until I turn the key off.

Whatz up with that?

BTW thanks for the link for the connectors Dan. 8-)
