• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Hi Guys

I asked this question earlier with no response so I had to do my own investigation and here are my findings for reference for anyone else who needs this info:

I wanted to power warning lights for my new TrailTech Striker - so I needed to know which pins in the pug at the back of the standard Husky instrument cluster fed which lights and how they worked:

This is what I've found so far after studying the wiring diag in the manual as well as testing with a multimeter:

Pin1: empty
Pin2: Brown/white - +12V when key on - some sort of switching circuit?
Pin3: Grey - I thought this was the fuel warning light - but the readings I'm getting dont tally with what the wiring diag seems to suggest?
Pin4: Blue - earth always
Pin5: Yellow/black - +12V always
Pin6: Black - speed input?
Pin7: empty
Pin8: empty

Pin10: Red/black - Turn signal
Pin11: Skyblue - Turn signal
Pin12: Red - Neutral indicator - switches to earth when in neutral
Pin13: Bright headlight indicator - switches to +12V when brights are on
Pin14: Black - speed input?
Pin15: empty
Pin16: empty
Pin17: Headlight indicator - earthed when key is off. +12V when key is on
Pin18: 9V when key on -I assumed this was the temp sensor but the wiring diag shows no link between the instrument panel and the temp sensor so maybe this is the fuel warning?

I'm reasonably sure about most warning lights except the low fuel indicator.
 
Hmm that grey wire (pin3) is being quite mysterious.... I thought it was the fuel reserve indicator.

I've been trying to simulate an empty tank by leaning the bike right over on a partly filled tank and trying to see if I get different readings.

At first I thought I nailed it but am not so sure now.

When the sensor is in air with the bike leaned over and the key on I get a reading of 11 or so volts (while the battery voltage was about 12.9V) so I thought that was the signal (although I was expecting continuity with earth from studying the wiring diag.).

But when I start the bike it drops to 6 volts? And when I try and simulate a full tank (although I'm not sure I have enough fuel in the tank to properly cover the sensor) then it gives the same sort of signal.

Why would a simply on/off sensor have a varying voltage? I would expect either on or off.
 
Just had another look at the wiring diag in the manual. It seems that there is a resistor between the wire that runs from the low fuel sensor in the tank back to the instrument cluster and one of the live wires for the headlights.

Not sure why that would be, but that might explain the weird voltage readings I'm getting?

As far as I can understand the wiring diag when the fuel sensor switches on (to indicate low fuel level), then it connects to ground/earth. But I'm not getting any continuity to earth on my multimeter when I try simulate that. Its a bit puzzling?
 
OK after some more tests I think that the fuel warning is actually pin 18.

With the key off I get 68 Ohms resistance reading which is the value of the resistor shown on the wiring diagram and with the key on the resistance drops to zero - although I still don't get continuity with earth.

Tomorrow I'll put a bit more fuel in the tank and see if it changes accordingly.
 
Thanks!

Can you confirm if it switches to ground when the fuel is low the wiring diagram seems to show that.
 
So, one of my Vapor dash lights is connected to pin 4 and pin 18. And it is always on while fuel tank is full. When fuel is low it switches to off. Any ideas how to make it work the right way?
 
Hi

I also thought it switched to ground after an initial look at the wiring diag. But I discussed the meaning of the 68 Ohnm resistor with my business partner who understands electronics and he told me I needed to wire it to so that the negative side of the warninging light went to ground. See the photo below.

My tank is empty/ish and the light is on so it seems to work. I havent tried fill it up yet and check that it goes off though.
 
Ok filled up my tank and the fuel light stayed on - bugger! So the setup shown above is wrong.

But after fiddling around testing I think I've sorted it now. See attached diag.

This is great info. So I am troubleshooting my fuel indicator as it does not come on. I tested the actual sensor and believe it is fine. Fuel indicator comes on during the instrument diagnostics. Do you know where that 68 ohm resistor is located?
 
Thanks for all of your hard work. I need to install a new gauge set as well.

What is the orange wire?
