Mazda Electrical Problem... No accessory power

Hey,

I just re-did all the wiring from my battery. IE: to the fuse box, grounding locations, starter motor...

After I finshed, I turned the key and the motor will kick over fine... Yet I have no accessories power...

My stereo will not turn on, and I have an aftermarket volt guage that will also not function...

Though I have constant power to my stereo headunit... just not ACC.

I double checked all my connections and everything seems fine, What could it be, and where should I look.

I have already checked all fuses etc...

Thanks Greg

where did you start to rerun the cabling from?

The batt is still in the engine bay Nath... Just moved slightly to clear the tubs...

Ive come to think it must be one of the wiring harnesses, maybe got disturbed whilst tubbing the front end... Im gonna check them with the voltmeter to see what I come up with...

I checked the barrel today...

Ive got ACC power there... So I began to trace the wire as far as I could get... removing half the dash as I went...

Every ACC power wire has power, except the wire that provides ACC to the stereo Headunit. Which I cant fully trace without pulling the entire dash out...

So I think I will just run a new fused wire to the headunit... Should get me out of trouble.
