While ago I had a strange electrical problem, renewed connected cleaned and added earths and was well.

Started up for a ride out and the bike wouldn't pickup on the throttle, I knew straight away it was back!

Seat unit off indicator relay making buzzing, indicators flashing fast, temp gauge jumping with the indicators, no revs bogs down. Tap the flasher unit and its fine for a second then not, then not at all.

Replacement flasher unit came today straight on started revved great off for a ride don a mile or so great but then noticed indicators flashing fast again, close to parents house so managed to get there.

Seat off disconnected flasher, checked connector ign on temp goes to max soon as lights are on or bounces with the indicator. Flasher unit buzzing then fine and all works the not. Cleaned up connector all looked good, done the same with reg, checked indicators all flashing as should. Seat back on started bike revved fine everything working. Let it warm up a bit still all good. Ready to pull away and no throttle, bogs down checked indicators flashing crazy again

Had to leave bike there and get back home heading over to check it out agin in a bit, any ideas please?

bad earth somewhere - is this an LED relay?

I'd go with a bad earth/ live grounding out in there somewhere. Might sound daft but check the bulbs and bulb mounts, I've had an issue before with them being all corroded and that caused weird symptoms. (Mine went 'odd' after the bike had been washed!!)
Good Luck.

check the fuses are not only connected but in properly without dirty contact, dont forget the main 30 amp fuse, can easily play haywire.

temp jumping to hot is usually classic sign of bad earth, there are not many earts on the bike so take em off and clean them up.

Thanks all.
Battery ground done extra on from bat to top side earth of back coil, the other side of that coil is earthed down to bat ground point. Cleaned up all rear bulbs and holders, all looked Brett's good, couple of lose grounds to rear lights, tightened.
Fuses checked cleaned and in, same for main fuse.

Ign on, indicators flashed good temp gauge stable. Gear on, started up revved good went for ride all good, smooth revved well, indicators fine.
Decided to pop the headlights on as a bit dull out and the temp gauge went up, turned it off as didn't want to break down, home just down road.
Got into my drive safe so tried side lights, temp gauge started to go up, maxed out, main light temp went up about half, tried indicators same time flashed ok but noticed temp bounced as did the rpm needle as I was at idle?

Still revved fine seemed ok apart from the temp gauge thing?

Add another big earth? Where to from?

At least I got the bike home but don't want to go out this weekend for a proper ride and have issues.

The only wiring loom earth lug that I know of is at the front left engine mount plate next to the ignition coil. I suggest you start there and check that there is only 1-2 ohms resistance from this point to any of the electrical units ie the flasher relay etc.

Thanks magg hoped you could help.
So stick a tester point on the mount bolt then which wire of the flasher unit, disconnected or connected, ign on engine running?

Cheers

Ignition OFF and electrical units, eg flasher unit, can remain connected. Set multimeter on 200 ohms range, black probe on wiring loom earth lug at right front chassis connection point and red probe to the green wire connected to each electrical unit.

Resistance between all green wire connections points should be 1-2 ohms and chassis to green wire connection points should also be 1-2 ohms.

As you appear to have a number of intermittent faulty earth connections, either the main earth point (lug) is the issue or there is a common joint in the loom that is the problem. With the probes connected, more the wiring loom around to see if you can induce the intermittent connection.
