You will understand fully one day, at the side of the road, waiting for a tow. The DME relay is actually a dual relay, for both the fuel pump and the injectors. It is also a notoriously high failure item. I trust your soldering skills implicitly, but you will feel very foolish when this $30 part strands you. Everyone I know that owns a DME controlled car carries a spare.

As I best remember, the starter terminal 50 should have a 4-yellow wire harness connected to it. One of the four wires comes from the luggage compartment (where it connects to the ignition lock terminal 50 and the DME). You should be able to find easily the wire branch terminal -inside the luggage compartment (located on the driver side -near the fuse box) and measure the voltage (starter not engaged, engaged, A/C on/off; heater-blower on/off (lever heater contact on/off)

all above is great info imo.

Stock solenoid v feed sucks.
Every connector is a voltage drop. A solenoid can draw more amps than designed under circumstance. The main engine connector is great quality when it's kept clean. Its silver coating is great. There are other connectors elsewhere including after market alarm starter kill. The stock wire gauge is undersized for long life imho. The potential demands on the circuit are huge.

A $20 75amp Bosch relay fitted in the tranny tunnel or a new wire from ignition switch to solenoid is a fix. My 8 ga yellow will be hard to miss but I'm leaving another 1.5 ft in case I'm dropping engine and I forget to disconnect it. :D


all above a rant


ps:
"Tin Can Sailor"... was a little offshore on a snotty day with a bud who told how they sometimes let him steer the helm on a destroyer during 'Nam days.. great stuff.

Yeah, sometimes I think we spent more time underwater than on it. :eek:

Here's my old can on a calm day:

if that's the Fletcher class he said something like it was sometimes like driving a roller coaster in weather..

Sorry for being slowed, I have one more question. Why AC, heater, and any other component (other than a starter) is connected to the yellow wire? Is it to turn those components OFF while the car is cranking (in case any of them are on, such as an ac is on before starting the car)? When the car started, key is back to position ON, those things are back on?

You gave the answers to your own questions... (yes)

Adams class, but still a roller coaster underway. She had no stabilizers, so the roll was horrific. We used to hang a pendulum from the overhead on the centerline and place a degree wheel behind it to see the roll. Most I endured was a 45 degree. Doesn't sound like much, but they said the gun mounts would fall off at 56. :eek: We took plenty of "green water" over the bridge.

Her final voyage ended off the coast of San Diego.

Jascha,
Thanks.

This is a strange looking submarine.
