Bike DEAD
 

Morning guys!

Maybe someone out their can help. My 1990 3AJ Tenere wont start. Its stone dead. No light come on, nothing! I've had a new battery fitted. A new voltage regulator fitted, new starter switch fitted and some rewiring done. It will run after its been worked on but wont start if I leave it for a few days! This is so frustrating...I've run out of options...I match box is my next option if I cant get this problem solved...please help.

You say that it will run, but how did you get it started? Or was this only after you go it back?

Check voltage across battery terminals It should be around 12volts. If not, take it out and charge it (if it is a wet battery, check the electrolyte level)

Check the main fuse (normally 30 Amps: don't know where it is, though). If blown: replace

Check all the connections: especially those that were touched when doing the work.

Is there any damage to the ignition key slot: perhaps it's a mechancl break in there...

If the fuse and battery are OK, when you press the starter button, do you hear a click, from under the seat area? This would mean the starter solenoid: enough volts to activate the solenoid relay, but not enough to turn the starter. If you do hear a click, try giving the solenoid a tap: it maybe stuck.

Can you get the bike running by bump starting it? If you can, I suggest measuring the voltage across the battery again. It should read 12volts, but rise to about 14 volts when you rev the engine and the alternator puts out more juice...

That is all I can think of for now. it is 90% likely to be a simple fault/ loose connection.

Bike fine - bike electrics worked on - bike not fine - it points to a fault in the components that were touched...

thanks HTH
 

Charged the battery and checks all connections. Found that the fuse was blown (24 Amp). Is that the incorrect fuse? Should I rather use a 30Amp fuse?

Thanks for the quick reply!

My manual gives the main fuse as 20A.

Glad you've made some progress.

If the fuse blows again you may have a short circuit somewhere.

As for the fuse rating I would say take Blackdogzulu's advice or call a dealer as i do not actually own model: I was just going for the usual suspects!

BTW (by the way), HTH stands for "Hope This Helps" rather than my initials!!:D

Let us know how you get on!!

20 A fuse it should be
 

20 A fuse it should be.

"Had some wiring done" is the clue, I think. A simple short will blow the main fuse (20A, I checked) and bring the whole bike to a dead stop. Mine was found (after a lot of searching) to be in the headlamp cowling, where a wire was chafing on a bracket. It was part of the lighting circuit, so it only blew when I turned the lights on. I would fit a new fuse and it would be OK for a while, then it would blow again. I assume that the short was intermittent, and movement of the bike was what made the contact and blew the fuse. If you have had work done on the wiring, that would seem to be the obvious place to start.
