Voltmeter install question

[peng155]

Hey Guy's

I'm thinking about installing a voltmeter into my 71 "Z" to monitor the health of the charging system in the car.

The ampmeter only can tell me so much, but the ampmeter along with the voltmeter should give me a better picture of what the charging system is doing when the car in running...

What I'm not sure of is where to tap the voltmeter into...... I'm thinking of connecting the voltmeter at the alternator output post.. my other option is to tap into the electrical system somewhere that is on when the ignition is on.

Looking for opinions on what you guys think...

thanks

Run a leads to the battery posts for most usefulness.

This will tell you the voltage when cold (battery condition) and also the charging voltage (alternator/regulator functioning).

You can run a separate lead to the coil +pos and install a switch in the dash to see the condition of the ignition system if you need to ever investigate in the field.

You can run another separate lead to the starter motor and install a switch in the dash to see the condition of the starting system if you need to ever investigate in the field.

That sounds like a good suggestion Blue.... Thanks
