Up date.
Well I took everything off I could find including the battery. Did the continuity green?black test on the loom and couldn't find anything. Put loom back on and fuse NOT BLOWING ,put together rear light wiring , tested , Ok switches OK horn ok everything else all ok . A eureka moment fuse still ok . Now here is the next problem , what the hell is wrong now. Nothing works no horn, starter, dash lights rear light Nothing. What the hell have I missed. HELLLLP!!!!! Done Battery test and 12v 19

Thanks Toko Jo I know Ash , I'll give him a call.
As for other suggestions. Yes battery is the right way around The plug it in and one at a time theory is great if the fuse doesn't blow but as its still blowing it won't find it. Still head scratching cheers 21

Thanks for your thoughts. Battery off over winter on optimiser.
Motobatt , seems fine. I took the loom off last night and externally looks fine I assume I have to unwrap it to check every wire. That's the bit I can't get my head around , it was running fine 22

Nothing is left connected so my thoughts are melted loom for some reason. To me it's the only logical answer now. I'll try and get time in the next week to take it to bits I'll report back when I have done it .cheers all

Cheers guys
Already removed the regulator and andrectifier. It really is looking at taking the loom off and seeing if I can find anything. Cheers all 24

Brand new loom fitted last year when I gave it a tidy up .
Yes correct fuse fitted . As I have said it ran perfectly last year and something has gone ary while standing . Just don't know where to look now. Nbefore getting silly and replacing everything again 25

Not done any work since last ride.
I have disconnected every wire I can think of and it still blows as soon as I turn the key, or cut out the switch and " hot wire-" If I got to the situation when the fuse didn't blow I could start adding wires until it went again but not there yet. What else can I disconnect? 26

Hi All
I have a problem with my 72 500/4.Went out on it last year and everything perfect. This year turn on ignition and dead short somewhere, frustrating nightmare. Gradually disconnected areas of wiring, handlebar switches, rear light, horn regulator, etc and finally every connector in the headlight. Thought it could be solenoid so replaced that, bypassed ignition switch , still doing it . any thoughts pleeeeeeeese! Rich 27

Hi All
Not been on here for a while. Fed up with carbs clogging up through lack of use. Do you winter store with carbs and tank empty or just carbs Cheers Rich |
