Hi. I decided to change the HES on my 66k RT before it gives up. Just wondering how do I know it's in the correct spot. Seen a video on you tube where a guy had a fancy box with led's & switches on it. Was told of a technique where to turn over the engine from the crank pulley & fuel pump kicks in at TDC, but no matter where the HES is adjusted to the pump kicks in at same spot.
