I have a E-pump hooked up, but when I hit the GP switch my voltmeter dumps hard. I have 2 new (reman) optima red tops, new cables, new starter as of today. Never had this issue without the e pump. Makes it so if it doesn't start within first few spins then the batteries sound weak and the pump sounds like its cutting in and out. It's been 20* here and today left me stranded (old starter).
Alternator reads 14.2 at idle (no accessories)
Batteries 12.4
Thoughts? I want to put the pump on a switch. So it off when cranking.
