Thoughts please I thought it was a fuel pump issue, which is still off the bike. Then I thought it was the fuses which are now all checked and sanded clean. A full tank of fuel and 30 miles and lot of smiles later I parked her up overnight. She now starts with a good healthy vroom ;D then drops off the revs and sound like she is only working on one cylinder (to my ontrained ear) or could be just dog rough with the neutral light flickering. Adjusting the tickover screw has now effect. She then burbles on for about 5 minutes, started again for the same and then stopped and this time with now no indicated power ie no neutral light, headlight horn etc. any thoughts please? Cheers Roger

Hi It sounds to me like you have got an electrical problem.But I would not know were to direct you to look.Hopefully one of the other guys may know.

I know it sounds a bit obvious, but what condition is your battery in? I know you've checked the fuses etc., but how old is the battery? Is it charging and holding its charge OK.....?

I agree with Pops however, I'm afraid I still belong to the school of thought that Electrickery is black magic so not much help, but here's some thoughts: Voltage Regulator - notorious on NTVs - poorly placed, lack of decent ventilation, easily gets full of crap. If they get too hot they don't work, but not sure what symptoms you would get. The 4 pin connector for your electronic ignition system - did you check this when cleaning up your fuses/connectors? If memory serves me correctly, the lead runs from the front of your right hand (clutch) engine cover up the frame to a connector near the front of your petrol tank. Worth taking apart, cleaning and a smear of vaseline. - Not likely to be your current problem as this is more likely to give a running engine, or no running engine.

Cheers chaps, that gives me a few more things to check. Looks like I could be on the push bike for a while. ;D It is good to have a bike again, even if it has turned into a project sooner than I had hoped. Washing and polishing was about my limit LOL but I am learning fast. All contributions welcome, if we throw enogh ideas at the old girl she should run again. Ride safe. Kind regards Roger

;D ;D You guessed it she is back on the road ;D ;D My new mechanic came round to the house today and opend up the loom backed up with meters and probes and checked for damage then cleaned earth points and all plugs. I do not think the headlamp had been opened in years, complete with cobwebs! As each plug was cleaned the meter readings inproved and did not eventuall drop when started, then started to charge the battery. The neutral light also stopped flickering. She now ticks over well again and was still pulling at an alleged 100mph this afternoon Hope this is of interest. Thanks again for your help. Roger

rj2Para - A problem like that is my worst sort of nightmare. If it works it's fine, if it doesn't work you can usually use some sort of logic to try and track the problem down. But when it is intermittent like that, it is so frustrating. It looks like it was a cumulative thing, each connector adding its own bit of resistance till the system was barely working. Had it been left outside standing in the rain before you had it? With my last few bikes I have worked through the electrical systems when I first had them (once I knew they were running ok) and without disturbing things too much, have cleaned and coated the contacts in the connector blocks with vaseline to try and prevent problems developing. So far it has seemed to work. Nothing worse than an unreliable bike. I'm glad you got your problem solved.
Micawber.

Thats about it Micawber, she has lived outside for years under a bike cover, not ideal.
Assuming no further problems I will go with your idea and coat the contacts in the connector blocks with vaseline to try and prevent this happening again.
Just think how bad it could have been; it could have been sunny this summer and I would have missed all the dry roads. ;D
I was going to use my push bike to get to work in the morning just in case as I have not quite got my confidence back yet. But I could always start her and possibly ride round the block just in case ;D
I seem to remember a post the other week that also had a flickering neutral light? May be this would solve that as well.
I will keep you posted. Roger

Update,
The problem continued and required a new fuel pump.
Improved sound and general run but still electrically challenged.
She has been on the test bench now for about a week and is undergoing tests for a rec reg prior to replacement.
I seem to remember reading another post about these bikes being liable to rec reg issues so with luck that will see her running again in time for these winter rideouts :-)
I am still broken from falling off my push bike, just glad I did not fall off the motorbike. That must hurt more and I don't need more pain. :-)
Ride safe Roger

Sorry to hear you haven't mended yet, hopefully nothing too enduring. The running problem must be getting tedious too. I think the problem with the Rectifier is twofold - it's in a very poor position to get any chance of cooling airflow AND it's in a terrible position to catch all the crud from the back wheel. This lodges in the cooling fins and helps it all overheat. If the rectifier has burnt itself out, I believe they are common across a lot of the Honda range, therefore a second hand replacement should not be a problem. How to test it is beyond my knowledge - throw some old bones into a teacup and read the signs by a new moon is the best I can suggest Whatever it is, I hope it is soon mended and you're able to enjoy a ride or two before the snow lands (does it snow on the South Coast?)

Hi McF Just spotted your post sorry I missed it. The Weather is still very mild down here. Not that we ever get much down here. Dad says it's getting cold in Derbyshire, so I am glad I am down here. Random running continues but we are closing in on the little gremlins Roger

From past (recent) experience I think the reg / rec, if faulty, is likely to either undercharge the battery (if eventually goes flat to the point where the bike won't keep running) or overcharge (fries the battery). I can't rule this unit out but the symptoms you describe sound less likely to come from the reg / rec.
I've just bought a s/h one as a spare so if you need to borrow it for testing / elimination let me know.

Cheers Derek,
My mechanic seems to agree with you, but just in case we still need to go down the testing route I have an 89 Revere 600.
We looked at testing with an NTV rec this week but the connections are different, which is yours please?
Cheers Roger
