Electrical connectors

[franck]

I have been bringing back to life a 1985 K75.  All is running well but I am beginning to have problems with connectors - notably the gear position indicator connector (the one to the right of the battery).
I guess that there will be other connector problems as things shake down!
Can anyone recommend a reliable type of replacement connector and where they can be obtained ?  (UK or European supplies would be simpler.

My LED riving lights came with these connectors - I have had no problems with them in four years

Deutch connectors are the most reliable and serviceable I have ever used.  The downside is the cost of the tooling required.  The DT series will handle 13 Amps per pin / contact, DTM series somewhat less.  Overall a very high quality product.

Check ebay for AMP Superseal 1.5 connectors.  They are reliable water-resistant and cheap.  Many sellers offer packages of 5 or 10 for little money.  They come in sizes from 2-way to 6-way.

I too really like using Deutsch connectors.  Yes the initial cost is high.

Thanks you all for the information - after looking at the price of the crimping tools for the Deutsch I think I will go for a selection of the AMP connectors to cover the immediate problems.  wiring and connectors at 30 years old aren't at their best - may be winter rewiring project.
By the way if anyone is interested - I had a malfunction of the gear position indicator and after carrying out all the continuity tests and eliminating the console - I was planning a weekend to strip out the transmission to replace the switch.  However when making one more continuity test I noticed that just knocking the connector beside the battery sent the indicator into spasm. 
I have never had a motorcycle with a gpi before and this malfunction caused total confusion - the false neutral caused more stalls than I had as a beginner (being ancient this kind of thing give we geriatric motorcyclists a very bad name!)
Thanks again

The TGPI switch is in a very harsh environment, constantly exposed to rain and road dirt.  The contacts inside the switch can go bad because of this.  If you are seeing this intermittent behaviour, you might have to do the work after all to get the switch off the transmission and clean it up.  Read the procedure on this page: http://hrsbstaff.ednet.ns.ca/bvogel/K100/K100.htm

Deep down I suspect you are right - for me it is a case of 'if I knew then what I know now'.  This winter gone I stripped all the transmission to have check the clutch and a general spline lubrication.  I should have been a bit brighter and replaced the damn thing then....   ah well,  it's not to difficult a job.  My K75c came off the production line in July 85 which I guess makes it one of the first of the breed - a past time has become an obsession.
Best wishes

Water eventually gets into the GPI. When I replaced mine icoated the new one with Plasti Dip not too much around the mounting holes. The old one was able to be resurrected and coated with Plasti Dip. BTW the Plasti Dip was Red so you can change gears faster.

So, uh...if water gets in the GPI, say when you're washing all the dead bugs and roadkill juices off...will it dry out and start working again? Or is it pretty much shot?  I'm, er, asking for a...friend.

It can dry out on its own but on its own schedule. It isn't San Tropez down there. I don't know if the warmth of a hair dryer or a hyperventilating bunny's breath directed onto it would speed a positive result. Intervention might be necessary if luck doesn't work.

I pulled mine apart cleaned lubed and reassembled,  it's been sitting in my spares box for about 18 years. As per Laitch they will sometimes resurrect themselves and sometimes intervention is needed.  :dunno

I tried to find the switch on the MaxParts fiche, but my fiche-fu is weak apparently. Reading through the threads here on the GPI problem, it sounds like removing the rear wheel, final drive and swing arm are sufficient for gaining access to the switch. Yes?

Yes.

Since brevity is the soul of wit...  :euro


I was trying to figure out if I should do the shock/forks or the brakes next. Guess I'll wait until the next set of rain days and go after the GPI.


I had washed the bike and dried off as much water as I could. Thinking I didn't want water pooling/sitting in places I couldn't see, let alone reach, I took to the highway for a 90 mph jaunt. The truly weird thing is the gear indicator worked perfectly until I got back off the highway and downshifted. I had the green Neutral light lit and '0' showing in the display while sitting at what I know is a very long red cycle, so I eased the clutch out. Not easily enough, apparently, as the bike lurched into a stall. The old man in the SL roadster next to me laughed, but screw him (he had to slow down to 35 to take a twisty exit ramp that my frigging Grand Cherokee can do at highway speeds!). Anyway, upon re-start, the gear indicator was FUBAR. I get 3rd and 4th properly; first, second and neutral all show '0' and occasionally the neutral light comes on or flickers; 5th shows '4'.


So, somewhere between getting on the highway and just before the Old Man in the Mercedes laughing, the GPI went AWOL. Maybe this is a message from the G-ds, "Don't wash the bike."  :dunno2:

Fortunate to have a 88 K100 unfaired and a 92 K1100 LT.
Here they are.
