Title: Extra Earth
Post by: grog on Wednesday, 13 November 2019, 07:07 PM
Not sure if i posted this during apocalypse 14 episode or before. I added extra earth wire from battery to original ground. 5mm wire. Voltmeter ive fitted always bounced 13.6 to 13.9volts riding.  Now just steady on 13.8. Starting bike, turns over much faster. For a few bucks im thinking you should all do similar.

I added that same extra grounding ( and a few more groundings, ecu and clocks ) with the same result.

I had a triumph Legend - when it got hot all the indicators flashed because the earth went via the thermostat and it became high resistance. A separate earth wire sorted.  :)

Not a lot to photo. Around 300 mm of 5 or 6 mm wire. An eyelet connector each end, crimp or solder or both. Yellow was correct size for me. Wire just follows original earth from battery to motor.

Is that the small one off the batt that several people says fractures internally & has been the cause of hard to find issues?

Thats the one Hooli. Sure cranks over better.

I think Grog misunderstood. There are 2 earth wires connected (spliced together) coming off the battery. The small one has a connector and leads to the ECU (4 ground pins) and regulator/rectifier. The thicker one goes from the battery to the engine (as in Grog's pic).

Thanks Andre, i often get confused. Age does that.  :) Yeah the wire to motor.

Honestly Grog, at first I was confused just as you were. Slept a night over it and reread Hooli's post and got it. I am getting old and need my sleep  :cheers:

I couldn't 100% recall the details of the one I was thinking of, which I doubt helped either.

Cheers guys.

I think I should do this extra earth mod. When the bike is on the trickle charger I get a slight tingle when I touch anything metal on the bike. It's mainly if the soft part of my arm touches anything I feel it.

Maybe its just the tingly feeling you get when you touch someone you love. Just saying.  :laugh:

I had a go at this morning but ran into an issue. The bolt on the motor didn't want to undo. It loosened a little but then go stuck so I just nipped it up again. I knew if I tried to go more I would have a broken bolt. I ended up putting it on the fram behind the side cover. There is 2 spare holes, 1 either side of the bolt that holds the side cover on.

Just an update, putting the extra earth direct to the frame worked well. I no longer get a tingle from the bike when on the trickle charger. I also think it started easier/quicker as well, thanks for the post grog. 👌

Glad it helped. Id still be inclined to run another to motor.

Okay thanks mate, I'll make up another lead and run it to another spot on the Motor.

I have voltmeter on bars, used jump around a bit, after earth lead remains fairly constant. To me proves that i had resistance before.

At first there were no tingles/shocks with the trickle charger on, now there is ☹️. So tomorrow I'll have to get some wire and run another one to the motor..
