Help please: PDM60 & GSW-A (specific) question - trigger point

On my GSW I used the red/brown stripe wire as the trigger for the PDM60 - worked perfectly.

On the GSW-A, I no longer have a red/brown stripe wire anywhere that I can find - what has anyone else used instead?

The taillight appears to have a red/gray stripe which I though would work so I tried tapping in to it - the PDM60 comes on as expected, but then won't turn with the ignition. Once I turn the ignition off, the PDM60 continues to do its Christmas tree lights thing, until I physically disconnect it. Obviously the red/gray stripe doesn't do the same thing...

Search for my post on the same issue. I modified the can opener when I had the same problem.

I think I disconnected the red wire from the can opener and that fixed it.

This might help:

It may be more confusing that that - I have only the PDM connected, with +ve & -ve from the PDM to the respective batter terminals, and nothing else other than the failed attempt at the red/gray trigger.!

Being an electrical incompetent, I like to make sure things work each step of the way, so no lights, no horn, nothing so far...

As you might remember when you were so helpful for me wiring up some lights a few years ago, I'm not much of an electrical guy so finding an alternative isn't so easy.

There has to be someone out there who's installed PDM 60 on the GSWA as opposed to a GSW, and they presumably would've had the same issue.

Thanks anyway,

Alex

You did fine. You got it working right?

So you need switched power on your Wethead? It looked like Jarvis found a switched power wire on a small fuseblock under the seat next to the ECU. Not the taillight wire that you tapped into.

Picture from his thread:

On the GSWA the fuse block is in a different place, but doesn't have the red/brown wire. It does have the red gray one.

The GSW has both red/gray and red/brown.

You still don't have a voltmeter?

yes I bought a voltmeter but it doesn't seem to be helping me much.

When I tried tapping into the red gray wire, instead of the nonexistent red-brown wire, the PDM initiated with the ignition switch. Switch on equals PDM on.

However when I turned the ignition switch off the PDM stayed on well beyond the one minute I was expecting. Eventually I disconnected the negative to the PDM and sure enough the PDM died as you'd expect. When I reconnected the PDM, it remained off until I turned the ignition back on.

Short version: the red gray wire works as a trigger to turn the PDM on but turning the ignition off does not turn the PDM off. This seems a bit weird to me!

It takes about 2 mins for mine to turn off.

I forgot about it while having something to eat - it has remained on for about 40 minutes...

Problem solved...

The trigger that I used to fix the problem (after much digging around) is the red/gray strip with yellow dots for the tail light.

Thanks for all the input above and a couple of PMs!

Good deal! That should help a lot of new Wethead owners.

Alex, do you have any pics? I've triggered mine where others have and really don't care for the delayed shut-down.
