Following up on a earlier post, I hand checked the engine speed using a portable Tach and found it to be off.
Engine Tach showing 1500 RPM and the handheld showing 2000 RPM.
My Tach only has a 4 position Dip Switch not the more common 15 switch so I had Teleflex Fax me the setup sheet.
Now for the stupid question.
How do I know how may poles my alternator has ? This information together with the pulley ration is used to adjust the dip switch.
The only information I currently have written down on the Alternator is:
51A Motorola (Prestolite)
