2013 Race model

[Jakobi]

I don't think the US models came with the trailtech standard so may be limited replies.

I've noticed mine keeps going through batteries. The trailtech unit is a vector I believe and monitors voltage. If I turn the head light off it over volts the speedo unit and the back light dims. If the battery is flat the whole unit powers off. Its racking up around 50V from what I can tell before it cuts out. I don't believe its wired any different to my 2010 which likely does the same thing, but the unit specifies that its safe to 400V (AC/DC). New one not so.

Any ideas? Obviously running with the headlight on high beam reduces overall available power to the system. With it off its way up there.

The voltage regulator is shot, or has its cables disconnected. It sits just behind the right radiator.

 

[Jakobi]

So you'd think. I'm more under the impression that the wiring to the speedo doesn't run through the reg. This bike has done this since new and now only has around 45hrs on it. You'd also imagine if the reg was shot that the 50V of power shooting through the headlight would blow the bulb quickly. Not the case.

Wires up to a red wire/black earth, where all 12V circuits seem to be on yellow wiring.

I'm sure I've put the multi meter on the cables that power the speedo on my 2010 model at some stage as well and found high voltages coming through it.

Maybe the trailtech is connected to the full coil, the white output from the generator. Since the regulator is only a zener diode type it affects the all of the ac circuit and it would also bring down the full output to some degree.

[edit] (wrong) Or the trailtech unit is a DC voltage meter that someone connected to the AC circuit, causing it to misread.

Manual says input Voltage display is 1.6 - 52.6, and external power is 9.0-400 VAC (No Polarity), 9.0-55.0 VDC (No Polarity). One would assume it would be capable of displaying any voltage types than.

"Striker will operate on AC electrical systems but displays
voltage with less accuracy. (Not a true RMS meter.)"

Maybe the voltage output of the 2k3 without load is spiky and makes a proper readout difficult?

 

[Jakobi]

Thats what I thought. However when the voltage read exceeds the 52V it just shuts down and stops displaying anything at all, or dims the backlight if running on battery. Odd setup.

Mine is exactily the same, no idea why, had the same speedo on another bike and it didn't mash loads of batteries or go mad on voltage so it must be how its wired up. If you regulators broken you will pop headlight bulbs.

 

[Jakobi]

I think so Johnny. Glad to hear its not just my bike.

I guess I could always splice into a 12V regulated circuit if it was really worrying me. My guess is that the unit is shutting down as the volts exceed 50. Happens very quickly without other load/draw on the system (but may happen up in the revs when riding even with the light on). Then I would imagine it relys soly on battery power which is causing the shortlife span.

 

[rubber Jonny]

Sounds about right. I fancy tapping into the regulated circuit as i lose trip data when it goes off.

 

[wa_ndro]

Mine hasnt worked properly since day one. Trip meter resets everytime I start the bike, dont think the temp works, and they have a SERIOUS aversion to the slightest bit of water.
Disappointing really; thought trailtech made good stuff.

 

[Neil E.]

It sure sounds like it's wired into the system ahead of the voltage regulator. Might be worth trying to connect it in parallel to the headlight source wire. This would be whichever wire brings power to your headlight switch.

If the unit operates OK on a DC powered bike (try it on your Yamaha Jake), then adding a tiny full wave rectifier to only power the Trailtech unit might be another choice.

I've had no issues with the more complicated Trailtech Voyager on my GG (estart with DC).
