Let me ask a follow-up question to this statement.
Are you saying that I cannot wire in a relay between the 12v out on the controller and the 12v in on the pump (i.e., on the pump power wire), say using pins 85 and 86 on a standard Bosch relay?
I am planning out a system now, and my hope was to trigger another event via relay when the controller sends full (or near to full) voltage to the pump.
Is the problem due to voltage surge in the relay coil? What if I used a voltage suppression diode on the relay, ala this:
Relays
Or is the issue the internal resistance of the relay coil? (Perhaps tricking the controller into believing there is a problem in the circuit)
Would it be any different if the relay was wired in
after the pump (between the pump and ground)?
