I have an Evinrude 60hp E60TLCCR, the middle cylinder won't fire. I've swithced coil packs and plug wires, new plugs, new power pack and new wiring harness(needed anyway), I pulled off the flywheel, which looks new to me, outer and inner magnets look fine and the timer base moves freely. I ohm'ed the wires on the timer base and came up with 12.5, 12.6 & 13.1, the spec's I've found they should be 30-52 ohms, so I ordered and I'm waiting on a timer base to arive. Any other thoughts?
One thing that kind of bugs me is the key on the flywheel didn't protruded out as far as I would have thought it should. Anyone no the size spec on the key?

They do not stick out very far.----Note---- the key does NOT drive the flywheel.----It is driven by the locking tapers. Does spark jump a gap of 7/16" on all 3 leads ?----Have you done a compression test ?

The two other cylinders have good spark. I've switched the coils twice and still good spark on the two and not the middle. Haven't done a compression test due to the fact I'm not getting fire.

Get/make a DVA for your multimeter. Then measure the input voltage to the coils and the output voltages from the trigger windings.. That will point you in the right direction.

achris you are right! Put on a new (but used) trigger, no change. Time to stop guessing. Does anyone have plans to make a DVA?

Not sure if I did it right or not, I put the DVA adapter on my meter set it to DC, 200 range, placed the red led to ground and used the black to measure. On the input voltage to the coils, I measured at the orange wires going to the coils form the power pack, I got 4 volts on the two firing and 0 on the one that's hasn't been firing. The output voltage from the trigger, I measured at the concoctor between the timer base and the power pack (was connected) and had 14.9 volts on all wires. Bad power pack? It's brand new from CDI. :confused:
I also tested the brown and brown/yellow wires, connected, and got 15.8 volts. Am I not using the DVA right, why low voltage?
I also did a stator resistance check and it tested right on at 1.3 ohm's. Tested the rectifier and it tested good. I can't get the overheat warning to buzz, but I don't think this motor has the S.L.O.W. on it.
I am at a complete loss! :blue:

Update:
I tested the DVA from the stator with it plugged in and got 16 volts, unplugged it and re-tested and got over 180 volts, so the stators good.... Everything's pointing to the new power pack. Took the power pack off and the orange wire going to the non-firing cylinder was a little pinched, but not enough to cut. I sanded paint from the engine post were the ground wire connects between the power pack and the engine block and I've got all three cylinders firing! I'll take it out in the morning and see how she runs.
