/diy/ - Do It Yourself

I'm changing my alternator from a 60 amp'er to a 250 amp'er. As I'm upgrading my starter and wires anyway, I'd figure I'd add an ammeter. Independent of any specific brand of ammeter, in general would it be safe to put a -60/+60 range ammeter on a 250 amp system?

In terms of power usage, the stock starter only draws about 30-50 amps and the stock battery is a standard group 65 with 850 cca. The new starter only draws around 10-20 amps. I'm doing this whole job as a way of future-proofing the vehicle in case I want to use it to charge a lot of (4+ batteries worth per shift) of power tools. Also, the bone stock vehicle does in fact use an internally-regulated alternator and not an externally-regulated alternator or a generator, in case that information is useful. Any other advice would be appreciated.
