I gather from your description that yours is the older starter.
Its just a motor with the bendix on its armature shaft.
This one, the older, direct drive 27MT, draws about 30+ Amps
to close the contactor and has a holding current of about 12Amps.
The newer gear reduction, 28MT, starter draws about 100+ Amps
through its contactor and has a holding draw of about 20 or so Amps.
Both contactors have two windings, a pickup and holding winding.
Even the older 30 Amp one is pushing the limits of that under the dash
relay and its attending wiring under the dash.
Hard to describe via an email but hope this helps regardless
of what you finally do.
Am on the clock, have to get back to work.......
Over to you.

Ted H.
