XJ600 issues

[fromos]

Hello I have the XJ600 diversion 1992 model.

Problem started I rode around 50. Miles liverpool to whitchurch and as I was arriving at my destination lucky or not so lucky the bike broke down and wouldent start so I rolled to a safe spot and pulled of the seat to see my battery was smoking basically fried that moment I assumed the battery was fried after a roadside recovery agent came out it was confirmed he then told me my rectifier was more than likely broken and blown a fuse so the ten amp fuse went in and it was working of his 12 amp pack he said to replace battery and rectifier and so I did and same issue kept blowing the fuse even with the new rectifier and battery on and then the cdi decided to smoke bike was switched off and the cdi was removed and replaced again to test the bike no longer blew fuses but was only running on 2 and 3 plugs 1 and 4 not arking I tested plugs in 2 and 3 with 1 and 4 plugs no plug issues just coils presuming due to lack of arking so I've ordered coils but I really truelly believe it won't fix the issue and help would be great because I am at a loose end I've had plenty of suggestions wire arking out somewhere the loom is fried the coils blew in the process of the break down anyone have any ideas at all would be apreciated very much.

Phew.....that was one hell of a sentence.....

Anyway.....I'd be measuring the voltage at the battery with the motor running.......sounds like it could still be too high......or it was too high before you replaced the battery and reg/rec and it cooked all the other bits. But measure the voltage before you do anything else.....

yup I would be looking at the voltages to start as well as all wiring connectors to make sure there is not high resistance on any part of the charging circuit

as for the coils first thing is get a wiring diagram and see if you have a separate earth trigger for each coil to the cdi you could have fired the trigger part of the cdi for the coils

Hi it sounds like a duff voltage regulator or connections to and from it

this link might be of help

Apoligies for my awful punctuality I have a meter there I will give it a check but this is the correct regulater rectifier off a running bike.

But to be honest even after putting the new battery and rectifier on it was still blowing the ignition fuse and after the old cdi which I've replaced that started smoking its stopped blowing fuses and then stopped running on four cylinders so if I check the battery whilst the bike is on it should run no more than about 13 with the lights on if the reading is running higher I still have a charging problem ? And is it possible that one of the coil wires or both are fried ? Any idea why the smoke from the cdi ?

Smoke means something got hot, hopefully not broken!

These bikes blow the coils a lot I've heard.

But your issue sounds like the generator is at fault. It's blowing the rectifier and then cooking the battery.

Either that or the mother of all shorts.

When operating the battery works as part of a circuit which is why continual charging doesn't actually harm it. However if the charge sent to it was too high then it would pop the rectifier but if the rec hasn't blown it might just be allowing too much power through due to a fault on the generator.

I cleaned up all the eartj connections and terminals and no more smoking cdi which is a good sign we put a tester on the battery while the bike was running it was showing just under 13 volts that's without the lights being on I heard that goes down not sure if that's ment to be reading roughly about that anyways I am replacing the coil tommorow hopefully it runs on 4 as normal blows no fuses and the cdi doesn't decide to smoke if all is well it should be fixed as for the meter showing what it showed do you think that because the coils down its showing the wrong reading ?
