They are in parallel normally, but get in series at start. The left-side battery (driver side in LH cars) is not grounded to the body. Instead, it goes to a big cylindrical relay (covered by a square, black plastic cap) where the conversion 12 to 24 v is made. That relay is besides the fuse box.Much appreciate the time and effort . Quick silly? question
Is there an easy want to identify if I have a 12v or 24v system?
Without me crawling around under the car. Knees don't work to well these days.
I have twin batteries standard. They seem to be in parallel.
