S/W Volt meter wiring?

OK I lost (cleaned the shop) the damn paper work on a new S/W volt meter for my 56,its got 3 post Pos,Neg,and a center one not marked ..........where do they go,?? Thanks!

 

You only need + and - on any volt meter. Don't know what the center post is about.You might meter it when you hook up the other wires to see if its hot or ground. Could it be a mounting post? N.N.

 

Could the 3rd post be illumination?

 

center bolt holds the bucket...

 

no it has a light socket hole also

 

ok it also has two post for mounting,it has three others

 

As said, a voltmeter only needs a positive an negative feed to work. A pic would help.

 

here ya go

 

Does this work

thanks Im going to try it...............

 

I think Pete has it right....

 

If you are still worried, test the "dead post" with an Ohm meter, it should give no reading. If you are STILL worried after that, put in a fast blow microfuse on the + wire, so if its wrong, the fuse goes before the gauge. I'll bet the "dead post" has no reading.

 

Yep..that's how I always wired mine...

 

thanks guys............

 

No problemo
