I put on a new wiring harness today and it started the first try. I,m not bragging I,m just still suprised. I have a 49 8-n and the amp meter wasn,t hooked up. Where do I hook the wires to. One is marked pos. and the other is marked neg.

RDNCK..... ..If you have an original ampmeter, there should be a current sense "loop" on the back of the ampmeter which senses the electomagnetic field that surrounds a wire when current (amps) flows thru the wire. There should be NO physical connection between the original ampmeter and the battery charge wire. Its called inductive coupling for the technically challanged. (grin) Just pass/feed your generator output wire thru the loop, not touching anything.

Howsomever..... If you have a replacement ampmeter, the generator output wire must be cut and connected to the appropriate terminals on the back of the ampmeter. pos to pos or red to pos and neg to neg or black to neg.

Note: the ampmeter really don't care which way the wires are connected because it is a center reading meter. BUT you do care, if you want the meter reading to traditionally show positive when the generator is "gennin" and show negative when you left the switches on. If the OEM ampmeter, just re-route the direction the wire goes through the sense loop. If replacement ampmeter, swap leads on the back of the ampmeter.

Oh yeah, if the wiring harness is already split for a replacement ampmeter and you have a traditional OEM sense loop ampmeter, just pass one of the wires thru the loop and connect it to the other wire and of course, insulate it good so you don't do any arc welding under your hood.

Hope this helps..... .Dell
