Faulty Healtech Gear indicator

Remove the plastic sprocket cover. Below the clutch slave cylinder you can find the GPS. See service manual page 3-18 topmost figure, the GPS is the white thing, although it probably is not white in your bike but covered with dirty chain grease. Clean it first from outside with WD-40 or similar. Open the two allen bolts and carefully remove the GPS so that you don't lose the little parts, see the figure at the bottom of the same page. Check also that the o-ring is in place around the GPS. Clean the contact surfaces with sandpaper and reinstall the GPS.

It just came to my mind that you had some earthing problems. See @seth 's old post about that

Could bad earthing have ruined the GPS or its wiring?

You can perform a check for the GPS by measuring the voltage between the pink wire and earth within each gear. There must be a sufficient voltage of min. 0.6 V (except for neutral it's 0.0) according to the manual but IMO it also has to be different for each gear. Unfortunately I don't have a change at the moment to check it.

Thats all good thinking Tim, you could be right about gps. 👍

@Stevel3
When my Healtech gave false indication cleaning the contact surfaces of the GPS helped. I also measured the voltages both before and after and I noticed some change. So I suggest that you clean the GPS first and if it does not help, check the voltages.

Thanks Tim you've given me some great info there.

I was just told by the mechanic that it's drawing to much current which is why it keeps throwing the F1 fault light. He said he has spent a fair bit of time on it with a multi meter and that is what he found to be the problem. He doesn't seem to think there is a way around it. He did some research on the Web and it happens to these and other brands as well apparently . Anyone got any suggestions or should I admit defeat and take it off. Also this is the 2nd unit so must be something in my bike.

To me that means your generator and / or rectifier ( that converts the AC from the generator to DC) is faulty, not the healtech gear indicator.

Yeah I very much doubt it is the Healtech unit as it's the 2nd one. I asked the mechanic and he reckons everything is testing up as it should.

Drawing too much current . . . .     maybe check your wiring (on that circuit) for a possible short / leakage to earth, probably doesn't need to be very much out to throw the thing.  We're talking partial volts after all.

He reckons he checked it with a multi meter with it connected and said it was drawing more current. When he disconnected the unit it was in spec.  Would adding an extra earth help at all, I know I'm clutching at straws.

Well, to me that shows it's most probably something on your wiring (on that circuit) that's not insulated proper & is causing that 'leak'.   I think from memory you removed the unit by the clutch slave? yeah?  Well, if you did, I'd be checking that area as the most likely culprit, then the plug itself where the new unit plugs into. Something is allowing more current to flow when you plug it in, so, check the plugs & what they plug into.

Cheers mate, I have just unplugged it for now. Maybe later when I don't have the shits with it I will have another look lol. I installed it the way Healtech say to do it so yes I'm thinking there is a small issue somewhere, maybe around the black connector where it gets it's power from.

I'd check the earths, including the ones for the engine block. A poor earth results in a higher current flow as it tends to drop the voltage.

I did ask him to,check the earth and he reckons it's good. I'll get some more wire and do a second earth to the engine.

Such a stuff around Mate, wish i had an answer for you. Mine and Mates been faultless for long time, just checked, 6 yrs.
