550 amp dc ammeter guage

I am not having any luck find one in that range. Trying to replace the broken one on my battery charger. Approximate size is 2 1/4" square.
Anyone know where to get one?

I saw a lot of amp meters on Amazon when looking for something unrelated.

550 amps? Is that a typo?

Maybe it has a built-in tester?

Need a resistor shunt with a volt meter for that kind of A.

Not a typo. Posted another thread, looking for info for my old Rizk CH110, which that was what the old broken gauge read.
500 a dc is the largest I have found.

That was my thought.

OP have you checked if that meter has an internal shunt or an external one. If the shunt is external then you may be looking for a volt meter. IF so then what you may have is a volt meter that has the face marked for amperage reading.

no neat sig line

Maybe pull the meter and check for a part number.

I have a 500 amp shunt. It specifies a 50 mv meter. 500 amps = 50 mv.

My apologies to the OP and others for going off topic.
It seems this model had a boost charge (jump start) of 550amps at 12 volts. What would be the need of an ammeter for that purpose?

Just trying to get it back to how it was.

Can see the back of it without opening up. Only two numbers on it, one is a circle with a 69 in it, the other (not where I am right now), from memory was T113. I had hoped for a part number, but doesn't appear to be any luck.
