Will tech 1A test my RPM Needle Circuit???
My RPM needle had a good 'sweep' motion before I did resto on the I/C. Now it's 'jerky'. I think the DE Grease might have impeded (pun intended  the signal / circuit somewhere.................... |

I can't say offhand. The FSM should say? Does the needle self test when you turn on the car?

I'm with Matt on this one... What does the FSM say?
I know it can do a lot, tho... And there are some tests that can be done with the CCM directly. Also, with the needle, make sure there isn't any mechanical interference... |

DUH. Check GM FSM, to see if GM Scanner will do the test.
(that is, IF Techline Tech 1A is same as Vetronix Tech 1 A) |

Considering that Vetronix is calling their machine the Tech 1 A... I would HOPE it does the same tests...

No, it will NOT test RPM function.
Special tool needed J-33431 Signal Generator. But there IS good news; Techline is a diagnostic tool referred to on same page... Quote:
