RE: Question about computer module
jmpancoast, on illustration B-37 it would be the forth pin from the bottom, you'll notice there are 2 pins, then it appears to skip a pin then there is one and another skip. is that # 31?What does it do?

RE: Question about computer module
All I can offer is that if that is the corrrct pin, the wire should be blue/grey. If so, it is connected to the system relay.
Let me know if that is the correct wire color.

RE: Question about computer module
Thanks Bro, however the problem I see is the copper post that goes inside the pin broke off at the base inside the tab. Looks like its the forth pin up from the bottom of the connector tab in issustration B-37. if i'm right it is # 31 which says constant power. any idea what this constant power is?

RE: Question about computer module
Like I mentioned, it feeds the system relay. I interpret this to mean it provides power continuiously to the system relay. There are four wires to/from the system relay. Oneconnects to pin #4 on the ECM, one feeds the coil and the fuel pump fuse, and one is to switched power pin #13 on the ECM. The last is the wire connected to pin #31.
Is the pin broken on the ECM or on the PC-lll?

RE: Question about computer module
Its broken on the PC111 can I ride without #31 working? I found the pin and put it about halfway in the hole and plugged it back up. I imagine it may be touching the area it broke away from at the base of the connector. Bike seems to run ok....although I only took it around the block.

RE: Question about computer module
I wish I could tell you yes, but I don't think it it fixed to the point of being reliable or good for the bike. It is my opinion, you need someone to make a permanant repair of the pin which broke, or replace the PC-lll.

RE: Question about computer module
It sould be possible to find out how the pin locks inot the connector - unlock and poke the pin out of both sides, separate the pins from the connectors, and connect them externally from the connectors?
HD sells the pins that go into the Harley side connector, but it sounds like you need the PCIII side? Not sure if HD sells that "sex"?

RE: Question about computer module
In the boat factory we use a product called Boeshield, designed for watercraft and some aircraft application. Look it up at West Marine, it should be there. It dries to a waxy film preventing most water entry and corrosion. I've used it on battery posts and wire terminals.
