I've just done a search for vehicle and marine ammeters. The vast
majority are 30-0-30. A few are 60-0-60. According to you they should
all be 150-0-150.
If it were to measure everything in a modern car, it would need to be 100
0 100 or more.
But a pure analogue ammeter is very expensive to fit, due to the very
heavy cable needed to the dash. Hence them not being fitted these days.
You can measure the voltage drop in a battery lead - either plus or minus
- and calculate the charge/discharge current to the battery. But doing
this to sufficient accuracy to be of use, likely not cheap.
