Ammeter or not?

Hi Folks, I have a 71 K20 pickup that I have almost finished wiring up with a painless system. I replaced the 60 amp alternator with a one wire internally regulated 150 amp alternator. Should I leave the ammeter hooked up or am I in danger of burning it up. Anybody know what it is rated for? Thanks, Jack

I would not run it. Just do a volt gauge conversion or run a separate volt meter.

You ammeter is just a charging gauge and it only tells you if the ammeter is charging or the battery is discharging if the alternator fails. It is fused by 2 four amp fuses in the wiring, so It shouldn't burn up.

Depending on how the painless wiring circuit is designed the ammeter may or may not work. It may even be set up for a voltmeter. If you look at the page your posting on you will see a thread about two rows down that will give you tons of information on the ammeter. If yours is not wired like the original harness it will not work, but I think it is covered in that thread and if you need any help on wiring it right we will bee happy to do that.
