RE: [T3] Hard start relay diagram

relay wiring diagram?

I think you would have to know what relay you have... there are several
versions.

The basic concept is 3 wires:
1 input wire from battery connection
(often a ring to hook into existing battery connection on starter solenoid)
1 input wire from ignition switch
(often a male spade to plug the existing wire in)
1 output wire to starter solenoid
(often a female to plug into existing solenoid connection)

On the early 6v Type 3s, assuming you have cleaned all wiring connections
and ground straps and checked your battery, I've found that usual voltage
drop culprit is:
1. The wire from the voltage regulator under the rear seat to the ignition
switch.  Run another wire under the carpet from regulator to ignition switch.
 Check/clean all your regulator connections first, sometimes they get rusty
if any water has got in there  (especially in Type 34s where the regulator
in mounted right next to the floor)
2. The wire from the switch to the solenoid.  Consider running another wire
from the ignition, under the carpet, through the battery cable hole, and
to the start solenoid.

Or install the relay (less work).

Or replace your wiring harness (lots of work)

This only applies when the car is hot after an extended drive or very hot
outside.  If you are having problems when it's cold, you need to go through
the system cleaning stuff and/or check your battery.
