Protec ignition conversion to mallory electronic ignition

[rshrews]

I have had some timing issues and now starting issues with my 92 sport. I have changed the plugs, wires, had carb rebuilt etc all in the last year and I am now convinced that my coil packs are going bad.

I have noticed on skidim they have a conversion kit for sale and I was wondering if anyone has done this before with their protect ignition.

If so..

How difficult is it.

Can someone leave a summary of the steps

Thanks PN Crew

I would love to help but mine was unfortunately done before I bought my 93. I say unfortunately because I would have liked to have seen how it was wired before and what to change myself.

Can someone with a functioning protec ignition at least post the correct wiring diagram from the coils to the spark plugs so I can rule out incorrect wiring before I drop 4 hundo on the new ignition system

I believe the protec wiring diagram is in the downloads section of this site or on CCF. One of the 2. I had to pull teeth to get someone to respond with the diagram in a similar post.

I can look tonight. I have a 92 ski with the protec still in place.

Thanks for the diagram TRBenj. I will have a look at it tonight

Ok one more dumb question for you guys.

How do you know if your engine is right or left hand rotation. I know my prop is right hand rotation. The tag on the engine that has the model and serial number also has the firing order which matches the firing order for left hand rotation ford engine.
Any other way I could confirm that the engine is a left hand rotation.

PS the wires were correct if in fact the engine is a left hand rotation

If you look at the engine tag, the second letter (after "P" for pleasurecraft) should be either a L or an R, this is the rotation of your engine. The letter following V (R or L) is your prop rotation.

So if the model number is PLP-PR-R12PT then I have a right hand rotation engine?......
and the wires are all mixed up?.....
And I could avoid spending $400 on a conversion kit and just correctly wire the plugs?....

RE: Protec ignition conversion to mallory electronic ignitio

I think I have answered my own question

apparently the L after the first P indicates the engine rotation and the R before the 12 indicates the prop rotation per the 1991 PCM manual posted on this site.

No sweat whats another 400 hundred bucks and an afternoon spent digging in a 351

HI,
I actually installed this Mallory conversion kit on rshrews engine today. However, I ran into a few issues. I cannot get the engine to fire over. WE have spark while cranking and 12v on the purple wire while cranking, but we do not have 12v on the '+' of the coil(purple wire) when the igniton switch is in the on position.

So I have a few questions regarding the wiring of this conversion kit as the instructions were hand written and a little unclear.

Distributor, Ignition module, coil, and plug wire install
At this step, I removed the mechanical pickup that was on the engine after setting the engine at TDC #1. I then installed the Mallory distributor with the rotor facing the 6 o'clock position as there were no markings for where #1 should start. So I then installed the plug wires starting from that position working my way couterclockwise in the firing order: 13726548
I then attached the purple lead from the new wiring harness to the '+' side of the ignition coil. I installed the other end of the purple wire in the harness to 1 side of the resistor along with the red wire from the ignition module. I installed the green wire from the ignition module to the '-' side of the coil along with the gray tachometer output wire. I then installed the brown wire from the igniton module to engine ground.

Starter relay wiring and 50 amp breaker
At the starter relay, I installed the main power wire from the battery to the positive side of the relay. I took a read wire and ran it from the same post to 1 side of the 50A breaker. The other side of the relay contained the heavy wire to the starter. I attached the white wire from the new harness to the 'S' terminal of the relay and the other 2 white wires to the neutral saftey switch. I installed the single black wire that came with the kit to the 'I' side of the relay and the other end to the other side of the resistor. I then took the 2 red leads and other orange lead from the wiring harness and installed them on the other side of the 50A breaker.

Alternator wiring
Pretty simple: The other end of the orange wire was attached to the B+ post and the yellow/green was attached to the Excite post and the black wire to the Ground post.

Now here is my problem. NO power on the purple wire when the key is turned to the ON position, but there is power on the purple wire when cranking. So I unplugged the 8 pin connector and check for power at pin 5(red) and pin 6(purple). I had power at both terminals. It is my understanding that there should be power on the purple wire until I jump power over from the red wire as the purple wire is power coming back from the ignition switch.

Do I need to hook up an ignition power lead to the 'I' terminal of the starter relay. Also, what is the purpose of the resistor and did I hook it up correctly?

Resitor wiring was black wire from 'I' terminal of the starter relay to one side and the purple wire from the wiring harness and the red wire from the igniton module to the other side of the resistor.

Any help would be greatly appreciated.
Thanks!

WEll today I contacted Ski Dim concerning the mallory distributor conversion. The wiring instruction they provided in the kit were very vague and after talking to them, I was able to figure out what I did wrong. It wasn't my fault as the purple wire from pin 6 changed colors in the taped up part of the wiring harness to red. So I ohmed out the wires and found which red wire the purple one changed into.

So here is how the wiring is supposed to go.

1. Main power battery cable to 'A' side of the starter relay.
2. Red jumper wire from 'A' terminal of starter relay to 'IN' side of 50A breaker
3. Red wire lead from Pin 5 of the wiring harness to the 'IN' side of the 50A breaker
4. Purple wire of pin6 that changes to red to 'IN' side of the Ballast Resistor
5. Red wire from the ignition module of the distributor to the 'IN' side of the Ballast Resistor
6. One purple lead from the engine wiring harness to the '+' of the ignition coil
7. The other purple lead to the 'OUT' side of the Ballast Resistor
8. Black jumper wire from the 'I' side of the starter relay to the 'OUT' side of the Ballast Resistor
9. Green wire of the ignition module to the '-' side of the ignition coil
10. Brown wire from the ignition module to engine ground
11. Gray tach output wire to the '-' side of the ignition coil
12. There are 3 white leads on the engine wiring harness. 1) to the 'S' terminal of the starter relay, and the other two white leads to the Neutral Saftey Switch
13. Orange lead to the 'OUT' side of the 50A breaker
14. Other end of the orange lead to the B+ side of the Alternator
15. Yellow to Green wire to the Excite post of the Alternator
16. Black wire to the Alternator Ground Post
17. Blue wire to the Oil Pressure Sensor
18. Tan wire to ECT Sensor
19. Red and Black spade connectors to the Carburetor choke coil

It took me 20 minutes to correct the wires and at the first try to start up, everything worked.

Hope this helps other people try to install this setup.

Later,
