help! 240Z isn't getting power

[Datsun240Z]

The story goes like this;

I bought a 240Z, plugged the battery in and everything worked (radio, tail lights, interior lights, headlights, dash lights, break lights, ect).

The starter motor clicked over but from bad terminal connection, that is as far as I got it.. until dad put the battery around the wrong way and tried to start it.

 

The starter motor still works (cranked it over by bridging it), key barrel isn't playing up, it blew the centre- left and right fuse and when I bridge a positive current to the alternator the car cranks over but none of the acc. works and when i turn the key, nothing happens.

 

As you can tell, I am new to Datsuns as my last resto was an 1980 corolla.

Despite studying the wiring diagrams and checking for current/continuity, I am clueless and need help, please ! 

 

If it gets to it, I can pay someone to come out and have a squizz at it/try and fix it.

 

Feel free to Text me: zero433713091

Or reply to this thread.

 

Thank you all !

I think Dimitri is good with electrics.

Hopefully he can give you some ideas... I'm a total dunce with electrics also. Although willing to learn.

check the fusible link at the positive terminal on the starter motor, i think you may have fried it

[Datsun240Z]

The fusible link after the starter motor has current going through it.

The red/white wire running from the dash to the alternator seems to be the problem.. there isn't any current coming from it and when we bridge it to the battery, the car cranks over and works.

On my 260z, the fuses are just in front of the brake booster. There is 2 of them.

ok that makes sense now the power runs through the amp gauge if the amp gauge its highly likely reversing the battery polarity fried the gauge

[Zedman240®]

Daniel is right on that one. I'd be checking the amp gauge; if that's open circuit, you get nothing!

 

240's are a little more simple in the wiring and with fuses. It only has one fusible link in line with the starter main power and fuses on the trans tunnel.

Got it !

It was the amp gauge !

 

Now I need to study as to why its not sparking !

Thanks to everyone for your help.
