Drogg1 if you look at your diagram BATT output(M) to starter is connected to S terminal. I just checked with my DVM and there is continuity between S and BATT output, not BATT terminal
The S terminal just pulls the round copper piece to allow the power of the battery cable pull the coil to engage the starter gear and turn the starter motor. With the remote solenoid the battery cable is powered when you turn the key to the start position. With the power being fed to the battery terminal on the starter terminal from the remote solenoid there is no need for the S terminal to have any power. Go to 15:20 on this video and you'll see the copper part I mean. When the solenoid is heat soak the problem is the spring will not allow the copper piece to contact the S terminal to allow the battery terminal to do it's job.
That being said, the same moving parts of the starter solenoid are still moving with the added remote relay. The only change is using a heavier gauge wire to energize the circuit. I guess this heavier gauge wire is sufficient to carry the load of the needed amperage to overcome the resistance of the heat soak.
Thank u guys for all the input, we got the car home. We changed the batt and I had to go under with a screwdriver and jump the starter. Next day off I will check the voltage and get back to u. Thanks again.
