Testing a VW beetle OEM 18 ohm gauge and vibrator or 5.1 volt regulator/stabilizer.
The aftermarket 34 ohm gauge and 5.1 volt regulator/stabilzer will show the needle reading low by quite a bit.
If you use a modified regulator/stabilizer at 7.5 volt and the 34 ohm gauge it will cause the needle to read high and will peg the needle on full. Requires calibration to read correctly.
Measure the resistance of the gauge to verify.
