ETA: Ground cable was connected to the wrong ground. Coolant pump is quiet now.
Yesterday I connected my battery for the first time in 2 months, coolant pump came on as soon as it was connected.
I needed to charge the battery so disconnected the wiring harness going to the coolant pump.
This morning I disconnected my charger from the battery and measured the voltage on the 4 pin connector for the coolant pump. 1 was 0 volts and the other 3 were 0.1 volts. I saw that as good.
I disconnected my battery to installed the connector and as soon as I reconnected my battery, the pump turned on.
I need to purge the cooling system but I cant do that until I can manage the coolant pump.
Any ideas?
