so what happens if a modern high amp alternator is connected to this gauge? does it just fry the gauge or does the car catch fire? can you make an ammeter that can work with a higher amp alternator?

Asked by: Alan1972
We recommend using a voltmeter for that type of application.

Does this ammeter require a shunt?

Asked by: N129BZ
Thank you so much for contacting us. No external shunt is used with this ammeter. It should be noted that this is intended only for usage with vintage alternators - it will not support the type of current generated by modern alternators. We don't recommend much more than a 40 amp alternator with this gauge. Hope this helps!
