Wouldn't surprise me either.

If you want the actual instructions, call SkiDIM! I never installed one, not sure if I ever saw the instructions with my own eyes... Though I did have a few conversations with Vince regarding general PCM wiring (not specific to EI), it's been 10 years since I created that diagram/picture.

I want to see the document, not talk to someone on the phone about it. Does he have the Prestolite instructions filed away with the Dead Sea Scrolls?

No the Dead Sea scrolls have been found. I think they were stored in the Amber Room.

He can probably fax it to you- they've sent me diagrams in the past. Or maybe they can email it now. You can try communicating with them telepathically, but it's probably quicker to call.

Tim,
Fax or email, when you do get it in, make sure you post it. Also create a link in the FAQ thread.

I'll cal Vince next week, as I can't stand this threadjacking cliffhanger!

Not going to post copyrighted material though.

I did look at the install data on the blaster 2 coil & it says to use resistor for 'points or amplifier circuit'.

I bet I got away with it for 400 hours because we never run more than a few hours at a time, & temps here are rarely above 90F.

Chris, the Prestolite may be like the Pertronix Ignitor II in which it doesn't require a minimum resistance, but I suspect it does.

No harm in scanning and posting copywrited material.

UPDATE ::

The nautique was on the lake today and runs AMAZING - thanks to all your help everyone!

I pulled the gas tank out last night and emptied it, a lot of 'junk' in the bottom of it.
Bought new gas line at the marina today.
Got home and decided to remove the 90degree fitting at the top of the pickup tube (as seen in pic in earlier post). The fitting had a screen below it and it was PACKED with leaves and debris. Cleaned it out, new fuel lines installed and fresh gas in a clean tank....
ALL IS WELL! Boat runs GREAT.....I love these things!!!
Thanks again!

Called Vince.

FYI, Vince was great, spent >5 minutes on the phone with me, reading off the Prestolite EI Installation instructions & helping me interpret them, all with no sale in sight.

Presotite recommended a coil with 1-2.5 ohms primary resistance & no ballast resistor in circuit.

According to Vince, most Prestolite EI module failures happen when guys put Accel or blaster coils with it

He said if my coil wasn't getting hot, it is OK as is (without resistor).

Just for kicks, I might use my IR thermometer & check coil both ways.

Hope this helps everyone!

Glad the instructions address resistance. So even though you know you're below 1 you're relatively safe until things start to heat up. What exactly is "hot"? Coil temperature is an odd way of monitoring the module, just wire it right and don't unnecessarily damage anything. These aftermarket coils can take the heat, the modules can't.

Know your coil resistance!

In a ski boat I'll take reliability over maximum performance any day. Excessive current and heat will eventually kill electronic components.
