The car is a 1971 240z built in March, I think it was on the plus . Dave
-
Can someone tell where the blue wire goes to the coil plus or minus? Dave
-
(secondary condensor in picture) with the blue wire ,does this go on the neg or pos of coil. Dave
-
can you tell me where the small condenser thaht sits on the top leads to neg or pos. I think my condensor goes to pos. Dave

Your ammeter should read between .3 -.5 ohms with a voltmeter. Your dash is feed through a 10 gauge white wire (+12volts)through the ammeter and out to a white and red strip 10 gauge wire. This wire is what feeds the fuse box which feeds the gauges. I would check resistance in all the coils and try to feed 12volts in each one. Dave

Problem solved. Ammeter in the dash does not like reverse polarity. It melted the coil that moves the dial. The main voltage runs through the ammeter first before feeding the rest of the car. Check the drawing.I have pictures but don't know how to but them into the post. Dave

Was reading post from helopilot, who had the same problem. It ended up being his ammeter (Continuity). But a new one in and it worked. Dave

Thats will be my next move.Has to be the problem if reverse the polarity.Will let you Know. Dave

So do I replace the Alternator Dave

Just checked it with a test light good. According to the diagram the white were talking about goes to voltage regulator , thats good then goes through the fire wall tested thats good . So I'am at left hand side underneath the glove box with the white fusible link (white wire) turning my test light on. This wire also goes to my ammeter. there is a heavy white/red wire at the fuse box that is dead at this point. Does not show any fuses to the fuse box. Dave

I put the battery cables on the battery wrong. Now I have no electricty to the car. Battery has been charged and 12v is at the starter. Jammed a screwdriver between the two leads on the starter and the engine turned over. No voltage at all inside the car. All fuses inside the main box are good. Is ther any other fuses I can check.
