Hey, everyone, don't get me wrong. I'm not knocking the PCIII's -- mine runs great with it. I've just had bad luck in getting two problem units in a row. More than likely the third will be a charm. I've also heard that bikes of my vintage with the MM EFI can tend to "eat" PCIII's. Don't know if that's right or not, but could be. JMHO.

 

I didn't take your post that way Tater, hell, you've got every right to be pee-oed! But that's what you get for trying to make a "dragstrip hotrod" out of your bike!! haha! [sm=joke.gif]

 

[sm=wootwoot.gif] Man, I'm just glad I found the real problem. These electrical things can be a bear. It's all good, BGHV.

 

Two things you need to check with the PC3 , first, make sure your battery is good and fully charged. Although it might start your bike it won't run your PC3. It draws more current than your ECM. Also the second cause of this problem with a PC3 is the CRANK POSITION SENSOR, although your ECM will work with a sensor that is less than perfect, your PC3 WON'T. Check both you will find out it's not the PC3.

 

Don't know, Johnny, could be I suppose. Battery seems to be rock solid, though. Plus, previous time this happened they ran diagnostics on the bike and nothing came up, so they thought the CPS was good. When I contacted Dynojet they suspected a bad wire in the PCIII cable and told me to send it back, but I've been waiting to see if it would happen again -- just didn't want to be without the bike for 2 weeks to get it replaced without knowing for sure. I'll have it replaced now, though, and if it happens again, then I'll start with the sensors, the CPS being the first to replace. Thanks for the ideas!

Funny, 'cause I was thinking that it might have something to do with your Mm EFI, also. I don't know much about them, or EFI on a Harley, in general, but that was the first thing I thought of. I hope the third time is the charm for you. If not, convert that sucker to a carb, LOL.

Well butter me up and call me Garfield, cause this p___y will be carrying tools when he rides from now on! Sure beat the hell out of another $150 tow bill!
[/quote] Taterdog, I have discovered the secret of quickly undoing the PCIII connections without any tools what so ever! If you will send me $10 cash, I will reveal this sensitive information that the Snap On, Cruz Tools and Major Tool manufactures don't want you to know about! (and yes, I'm just kidding). My dynotuner (DynoGuy) says that the first thing to do if you have engine problems is to disconnect the PC and try again. This way you begin by confirming/eliminating something easy to diagnose. Ride Safe!

 

What johnnyg said. I have had two problems with a pc on my 60,000 mile bike. one related to a weak battery, and the other a bad cps. both need to be in very good condition for the pc to work properly, in my experienc.

 

Could the suspected bad connection be somewhere outside the PCIII? You said you unplugged the PCIII, reconnected the ECM as per stock, and it started. Maybe it would have also started if you had removed, then replaced the PCIII connector. Just speculating, as it seems unlikely you'd get three bad PCIII's when the vast majority have no trouble with them.
