Low voltage at pump, suspected aftermarket alarm

[Martin.p]

Then I removed the wires from the pump! and checked voltage!
And it read 12.3v
So the 9v I got befor when wires where still attached to pump must of been reading the voltage drop across the pump.

So low voltage at the pump is not the issue with its running.

In short I was doing it wrong lol.
I am getting 12v at pump
