Default checking ox66 TPS

The manual says to disconnect the throttle link rod at the #1 throttle valve, why? Next step
connect harness and meter, OK. Next turn the engine start switch on. Does that mean to start the engine or just turn to the on position? I take it to mean the on position without starting. The voltage should be checked with the throttle valves fully closed, so why the need to disconnect
#1. I'm not real good at the electrical end of things and I want to make sure I understand the
procedure.

You just need to turn the key to the on position in order to check the TPS.

The throttle valves aren't fully closed when the throttle is in the idle position. In order for them to close completely, they need to be disconnected from the throttle. Since the TPS feeds off the #1 throttle valve, that is why you need to disconnect it.

Thanks Tom, I just synched the throttle valves and the throttle stop screw is only touching the stopper
by about 3/4 of a turn. Does that sound right.

Do not start......when the key is turned to the on position it sends power to the tps. As stated it is controlled of the number one throttle valve. Here's and old link.........
