Diesel Alternator Tachometers .................................. alternator
NOTE: Alternator must have an AC tap, usually marked “AC”, “R” or “W”. If such a tap is not present, a local alternator repair shop can usually add one.
You will need to know the number of magnetic poles in your alternator.
Consult the alternator maker or local alternator repair shop if you do not know this.
Also, you will have to calculate the pulley ratio from crankshaft to alternator.
Tachometers are factory calibrated for several combinations of poles and pulley ratios, but in almost all cases you will need a Portable Master Shop Tachometer for initial calibration.
