[DML] Starter solenoid circuit mod

["Ryan Bennett" <rpbennet@xxxx>]

Here is the info on the starter solenoid circuit modification, taken from De
Gull Wing magazine V1, #7. I have made this modification to my DeLorean, and
it does seem to make for a more positive start (or maybe it's just my
imagination).

On early vehicles (prior to VIN 2547), the starter solenoid's operating
voltage, in certain conditions, was not high enough to ensure a consistant,
reliable operation. This condition was displayed by a voltage drop
characteristic in the main wiring harness on vehicles with slightly
discharged batteries. To correct this condition a starter circuit
modification was introduced into production starting at VIN 2548.

This condition is generally displayed by a clicking noise at the
solenoid without any starter cranking. If this symptom is encountered on
vehicles prior to 2548 the following modification procedure should be
performed.

1. With ignition switch off, remove the relay compartment access panel
behind the passenger's seat.

2. Partially remove the relay strip containing the starter relay (it is the
#10 relay, the second from the left along the top relay strip).

3. Disconnect the white/yello pigtail jumber wire from its relay terminal
(#86). Cut and move the jumper from its white/red wire connector.

4. Disconnect the white/red wire (which had the pigtail jumper removed in
step 3) from terminal #30/51 and connect to terminal #86.

5. Using 14 gauge brown wire, assemble a 12 inch jumper wire with 2 suitable
female receptacles.
Note: One of the female receptacles must have a locking barb for a
positive connection.

6. Connect one end of the brown jumper to terminal #30/51 of the starter
relay. Connect the other terminal with the locking barb to the battery side
of the 25 AMP speed circuit breaker.
Note: This circuit breaker has 3 brown wires wire attached, with an open
terminal on it's battery side.

7. Position and secure the relay panel, replace the access cover and charge
the battery if necessary.

I have made a simple diagram of the before and after states of the relay,
but didn't want to attach it to this message. If anyone wants it, e-mail me
and I will reply with the file as an attachment.
