  • 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 The previous version was outdated and no longer supported.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!

Vapor Display - Tach on 511

MY12 - TE511. When I picked up this bike I also bought a TrailTec Vapor, people couldn't get the tach to work on the Vapor 450/511 combination. I haven't followed up since then with the group.

Since then, anybody get the Tach to work on the 450/511 vapor display?

How and where did you wrap the pickup sensor wire to make it work?

I've got things pulled apart and might as well make the tach work if possible.

Thank you.
 
You'll need the tach cable with the wired in resistor.

You need to tap into the black/red cable in the ignition coil plug, this is pin 3. Make a de-pin tool from a bladed bicycle spoke if you don't have one. Remove the black/red wire/pin from the plug and wrap the stripped end of the red tach sensor cable around it, seal it up with bit of shrink insulation and put everything back. Tap the black tach wire into any ground.

This setup has worked without issue for me for the past 12+ months on a 2011 SMR511. If you do it right it's neat and clean.

I could never get the tach to work by wrapping the red cable around the spark plug. The spark plug/coil pack wouldn't even seat back into place and seal with the wrap method.

I've also got the lights tapped in as well, so have fuel, indicators, h-beam LEDs working. Can't remember off the top of my head the exact wires and you need to make up a circuit board to get the correct fuel light operation. I can dig up the schematic if you need.
 
Motstruc, are you wrapping the tach signal wire around the outside of the insulated coil feed; or, is it electrically connected to it . E.g. a soldered joint?
 
I managed to get a Tacho signal using the wrap method for my Apico hour-meter. What I needed to do was solder a much thinner tail onto the signal-wire as the supplied signal wire was too fat. I used a single core out of an old USB cable I had lying around. With this, I could get half a dozen turns around the lower end of the coil, covered with a layer of insulation tape all fitting snugly, without force, down into the plug tube. Works perfectly.
