So, I was going to try working on jetting of the carbs today. But, unlike the past several weekends, when I went to start the engine cold, it didn't fire. No attempt at trying to fire... I went inside to retrieve the Crane HI6 documentation and see what I could find out. There is a single red led. When I turn the ignition on, it lights up solid. Using the troubleshooting part of the manual, I determine that no fault codes are triggering. I check for spark using my timing light. I get none. The HI6 manual says to crank the engine over and check to see that the led blinks. It just dims a bit when attempting to start but doesn't blink. I check power (red wire) and ground (black wire) to the optical pickup. I confirm power and ground. So... I am thinking the problem is the optical pickup. I read where if the white wire it put to ground, it will trigger the coil. I switch my timing light to the high tension lead from the coil to the center of the distributor cap. I disconnect the optical pickup at it's harness connection - wires (red, black, white) go from this connection to the HI6 control box. I pull the trigger on my timing light and ground the white wire. The timing light flashes, and the led on the HI6 control box goes out. I remove the slotted disk from the distributor shaft. I reconnect the optical pickup at its harness. I hold the disk in one hand and the pickup in the other and simulate the disc rotating within the pickup beam. The light on the HI6 control box stays solid - it doesn't blink like the documentation says it should when cranking. So, the pickup just "went bad", right? Am I supposed to actually see a light beam when the pickup is powered up? Because I don't.
