Subject:Have I damaged my control unit?
From:Jeff Oxroad

I'm having trouble getting my 83.5 1.9L to start.

There are a lot of things to consider, but I have one question at this point
before I go further.

Having checked the fuel injection relays in the secret "high voltage" box I
may have donor something horrible--or maybe not.

In Bentely Fuel Injection, AFC System pg. 23.32: Relays Checking (with relays
installed)

I just read in Bentley "CAUTION: Do not connect any test light to terminal 86
of adaptor  C if control unit is connected"

Having not read that earlier I was seeing where there was power coming off
the relays with the ignition switched on. I had the negative lead from the
voltmeter grounded to the engine black. I checked to see if and where there was
power at the relays. All had power except the 87 of adaptor C. Thing is I checked
86 of adaptor C with the voltmeter and got a 12V reading. no sparks no
nothing. Seemed uneventful.

From what I read 87 of C should only be hot when the starter in running. I
didn't have a second person to hit the starter, so I couldn't check that today.

BUT the question is, what damage did I do by connecting the voltmeter to 86
on adapter C with the control unit still connected? And I should add I may have
checked it wit a test light as well as the voltmeter.

I know I haven't listed my symptoms of "no start" here, but at this point I'm
concerned with possible damage I may have just caused and we'll get into any
other problem at another time.

I hoping for the best.

Best,
Jeff
