Harley Question
« on: June 12, 2017, 02:26:26 pm »
Trying to fix a problem on a friends husbands Harley, and am seeing if any of you amazing folks have any idea/input.  2005 Harley 1200 Sportster Custom. Use left turn signal, blinks normal 4 times, then goes in hyper mode blinking. Turn on right signal, 4 ways go on. Bike has been to the dealer twice, to the tune of almost $600. While the signals never were fixed, they did make the speedometer and brake light not function. Owner fixed a pinched wire in the switchgear they took apart, so speedo works again. I fixed the way the switchgear was reassembled and fixed the brake light issue. Dealer said they THINK it needs a turn signal module. $160....but they aren't sure. Owner doesn't want to trust them. I am looking to get a hold of a downloadable service manual so I can study the wiring diagrams. But, until then..... Bike has self canceling signals, about 12,000 miles, no alarm.
Owners wife is my TBI therapist, and she is amazing (and swears she will have me riding again!) so you can see why I would like to help them.
Any ideas/thoughts/conjectures/spells welcome!  Thanks in advance for the help.

This is pre-Rushmore, so not CANbus. Which makes me think its a wiring problem of course.

Going into hyper-flashing mode is indicative of a) a lamp out or lost ground, or b) the flasher module.

Misfiring the emergency flashers also sounds like the module itself.

Has any modification been done to add a braking module which creates a flashing brake light to get more attention of drivers behind?

I'm surprised the dealer couldn't fix it, the Sporty is not a complicated machine. The wiring is pretty much exposed under the seat unless they ran them inside the subframe rails, which is entirely possible.

Get a multimeter and some wire taps and check inputs and outputs on the flasher module. That should tell you where the problem is. Chances are the module unplugs, so you can first check the inputs to be sure its getting signals properly. For instance, if the signal from the left turn signal switch is not constant when pressed, the switch is bad. Just work through it.

The best help you can offer is to get them to buy a Kawasaki...2 friends of mine this weekend needed help on the side of the road with their HD's, (2 separate incidents.)Still not a fan of that engineering. One required me to leave work and get a trailer and then travel a hundred miles, but I like to help.

Not exactly useful, and unlikely to happen. LOL.

The older a Harley-Davidson is, the more likely it will have to be fixed alongside the road. Starting with the EVO machines, culminating in Project Rushmore, those problems went away. But like the dealer mentioned in the original post, there is little defense against a shoddy or inexperienced tech, no matter what marque we talk about.

I had catastrophic gearbox failure because Myrtle Beach Harley-Davidson either didn't put oil in the gearbox, or didn't tighten the cover bolts to spec, or both. This is not an engineering problem, its a tech problem and it means even if I'm in Myrtle Beach again, I won't even buy a soda at Myrtle Beach Harley-Davidson. Though I take some responsibility, because it never occurred to me that on such a trouble-free machine (coast to coast 3 times) I would have to pull the transmission dipstick and check it, and check the cover bolts to make sure they are tight. I do that now, and probably don't have to, because Crystal Harley-Davidson in Crystal River FL seems to have done a bang up job rebuilding it and everything is as it should be.

Well alrighty then. We may be camping mates at the regional, so we can talk about that then and there. Back to the OP post, I think it was hit on that a good multi meter and thorough checking for pinched wires or bad grounds will find the culprit. I customized a '79 Ironhead Sportster that had been badly jury rigged but was amazed at how simple and relatively inexpensive some of the wiring was to replace and fix. The poor thing had actual wire coat hanger holding on parts and an oven mitt for brake line insulation as it was routed over the rear cylinder....

there....fixed that for you!   :rotflmao: :rotflmao: :rotflmao:

the only thing I'm curious about is why they don't take it back to the dealer and demand they do the job right.  while the modern HDs are complex ( like all the rest of ours), this really should be pretty easy for them to diagnose.  I'd be screaming my head off to them.  Besides that, most HD dealers I've been at (a couple when I owned my Buell) were pretty eager to help out with problems.  perhaps I was lucky with dealers around here.   :o

JR, checked all the grounds (my first thought) and bulbs. Fixed all the wires the dealer pinched. Dealer said they can't test the module, but I see online it is possible, so I guess that is next. No mods have been done to the bike. I saw on a HD forum reference to a turn signal relay (as opposed to the module). Any knowledge of that? Haven't found an online manual I am comfortable getting, so maybe a used Clymer. They usually have good wiring diagrams.

Sport Rider......would you REALLY want that dealer to work on your bike more? I know there are Kawasaki dealers I hate to ride near because I am afraid of the bad juju that might effect my bike!

Also have to check the speedometer, as I have read that some of the sensors for distance measurement for the signals are in there. A lot of folks online have had modules replaced and that wasn't the issue. Would like to save him some money if I can. I don't work on HD's much, but it's usually older ones I rebuild or help restore with someone. All the sensors for the turn signals isn't normal (for me). More BMW'ish. Not saying it's bad, just different, and feels more complicated that it needs to be (have had bikes since 1980 with self cancelling turn signals) I gather the module going bad is normal from what I have read. Also read I can pull codes off the speedo, need to look into that too.

Always did like a challenge! 

Keep the ideas coming....Thanks!  :great:

I guess I just vicariously share the frustration of the bike's owner regarding the incompetence of the shop.  I'd at least give them an ear-full to feel more at peace.

Good luck with the checks!!!   :great:

Oh, trust me, I understand that! I flipped on a shop after my wife had her 600 mile service done. Bike was sitting in our garage, and had some oil under it. Drain plug was only finger tight. I was hot. Not sure if I helped by exploding on them, but sure made me feel better!

Thanks, I will need the luck :beerchug:
