Many thanks Captain 80s and Grum for your help and guidance! Grum, I am forever grateful for educating me on how to use a multimeter! It seems to me that I may have a bad starter relay. The reason I thought that it was a wiring problem it is because I just replaced the starter relay with a new one after the battery melt down, but I got it on ebay cheap. Also, it could be possible that wires touched when installing the relay as the red cover had melted away (see photo). I will get a new cover as soon as the bike starts. Am I correct that a bad starter relay could stop the neutral light coming on? The multimeter results: 1. Grum, I did what you recommended it and I set the multimeter at DC 20V range then I put one lead on the yellow/red wire at the starter relay and the negative on the battery negative terminal. I pressed the starter and got no reading. 2. When I putted the multimeter on the yellow/red wire and red wire, at the starter relay, and I putted the negative on the battery negative terminal, the starter motor did turn over which gave me hope. Wiring: 1. The green/red wire at the starter relay has continuity to the clutch diode switch. I looked and looked and I was unable to find the neutral switch diode. Could it be possible that there is none on Irish/UK VFR_ As in the diagram that Captain 80s supplied there was no neutral switch diode. But I did put the multimeter on Diode Mode. I putted one on the earth of the clutch diode switch and the other on the earth of the neutral bulb and did get a good reading. 2. Interesting to see that the clutch showed continuity whether the clutch was pulled in or out. 3. The clutch switch was working. The side stand showed continuity on the earth wire with the side stand up and no continuity when down. 4. The neutral switch works fine and the earth green wire from it showed continuity up to the clutch diode switch, so do you think that a new starter relay would solve most of the problems? Many thanks to both of you!

Many thanks Grum! Apologies for my lack of knowledge and you’re right, of course, about the mode on the multimeter. The thing is that I seem to have current of 370 running each way through the diode. So, I am not sure if the diode is the problem and needs to be replaced. One thing that I don’t understand is that I am getting no continuity between the earth wire at the neutral bulb to the clutch diode switch. Would this not indicate that the green wire is damaged between those two points? Thanks for all your help!

Many thanks Captain 80s

Hi Captain 80s and Grum, I have got a bit of time yesterday to wok on the VFR and I did follow your advice Grum and I might need a bit more advice from you 🙂 1. I have checked the starter relay and I got a reading, only when I pressed the starter, on the yellow/red wire of 172 with the setting ACV in 2K. Am I doing things correctly? 2. The neutral switch is working. 3. I am getting continuity from the neutral switch right up to the clutch diode switch, however, I am not getting continuity from the diode switch earth green wire to the neutral bulb. I did run a wire from the neutral bulb and earthed on the bike and the bulb did work. Not sure if this confirms that I have a problem with my earth green wire running from the diode switch to the bulb. 4. I have checked the clutch diode switch and does not show any current flowing in neither direction. Grum, I could not find a diode mode on my meter, so what I did was to check the clutch diode switch with all modes that I had on the meter and no current was showing at all. So, I am presuming, there is a fault in the switch. The clutch switch, does it need to be Honda or can be aftermarket? Many thanks!

Many many thanks Captain 80s and Grum this is so helpful for me and have given me new hope that my Vfr will see Road again

Yes the headlight is dimmer but does not cut all the way out in fact the battery is not good at all so I had it jumped to a car when doing the testing on the vfr had it now for 25 years so I would hate to have to break it up for parts

Hi yes all fuses are fine when you press the starter absolutely nothing happens but yes the headlights do become dimmer Greetings from Ireland

Many thanks for taking you time to help me and tomorrow I will start again at the vfr

Hi no the vfr does not start with the clutch in or out or with the side stand up or down and neither in neutral or in gear. I tested the neutral switch on a voltmeter and, strangely, it did show consistency in and out. I did put the earth wire against the chassis as an earth to see if the green neutral light would come on and did not. Any thoughts would be great! Thanks

Hi all, Looking for a bit of advise. I have a VFR 750FL 1990 and my problem is that I nave no neutral light coming on due to a regulator overheating the battery. The bike will not start as she thinks is in gear. Tested the light green neutral wire from the neutral switch to the neutral light and DID NOT GET CONSISTENCY. I have replaced the neutral bulb as it was gone and the positive wire to the neutral bulb is showing consistency. I have tested the neutral switch and it seems to be working. My problem now is where to look for the most likely wiring problem on the light green neutral wire and an easy way to test it to see where the problem is. My understanding is that the green neutral wire goes into the wiring loop and goes under the throttle bodies, removing the throttle bodies would be beyond my capabilities and I am wondering if there is a better way to find where the problem is in the green neutral wire or if it is possible to bypass it. I have read in a previous post that the light green neutral wire goes into a relay switch, which is under the throttle bodies, so I am wondering if there is an easy way to test it without removing the bodies. And where is located? All the other electrics seem to be working except the two right hand indicators. I would really appreciate if anyone can point me in the right direction. Many thanks or
