Voltage Question


Recommended Posts

so i just purchased a used XS D1200 and i hooked it all up so my question is do theses voltages look alright

All measured with a DMM

Resting with car off. 12.8-9

idle. 14.1-2

full tilt. 12.5-9

keep in mind i have stock alt and stock batt up front with only 4 gauge cca to the rear batt (the XS) planning on getting some better wire soon and the big 3 done.

thanks in advance!

Looks fine to me.

Full tilt voltage could be better - but it's not bad either. I would suggest getting a better battery up front - that's dragging down the performance of the XS battery (stock battery has lower resting voltage)

Also: what amp do you have?

12.8 - 12.9 is perfectly fine for a resting batt, bad is when it gets below 12.5v resting (usually needs a recharge/ reconditioning)

14.1-14.2 is fine also charging

full tilt volage in the 12s just means you need more alt/batteries for whatever amperage draw you have.
