The V35 has a a voltage drop which is causing issues. I'm not sure if the fuse box is the cause but it seems a good place to start.
Has anyone changed the fuse box? If so did you use a generic one or OEM? (assuming they are still available)

Oddly enough, my V50 wouldn't start an hour ago. No response at all. I cleaned up all the fuses & sprayed with GT85 and that fixed it.

However I don't like that style of fuse having had endless trouble in the past with an MZ that used them and will probably fit a fusebox from Vehicle Wiring Products or similar.

I think Halfords also sell a generic 6-way fusebox that takes modern blade fuses. I still have the original fusebox in my SP and had to stop and rotate the fuses in their holders when I lost my lights the other night.

Thank you for the reply, I have been studying the VWP catalogue
As the OEM fuse box has inboard fixings,it is smaller than anything else I have seen. However if I am going to change it to something larger, I do wonder about fitting a six way fuse box and incorporating the starter mod fuse

I'm glad it isn't just me with fuse box issues

Thank you for the hint about Halfords stocking one

Yeah - the Euro style fuses are much maligned. It does pay to pull them out and clean them from time to time. Corrosion at the contacts each end will lead to V drop and continuity failure. Just keep them clean - I shouldn't be bothered to swap the box out.

All automotive fuses suffer from corrosion, I really don't think the later spade type are any better, certainly had problems myself.

I've never had problems with the blade type but have with the type on the Guzzi (and MZ). I think one problem is that the copper contacts lose their springiness the contact becomes minimal.

The blade type are essentially the same as Lucar connectors and the act of inserting the fuse actually scrapes any corrosion off. I accept if they're left in a damp atmosphere for years they will suffer. A bit of silicone grease helps.

Well I was losing something like 3 volts through just three lucar type connectors on the Norge, at fairly high current.

But if all Lucars were like that nobody would use them. It's like the old British bullet connectors that everyone swears at. In fact they're fine if properly soldered (or crimped if you must) and kept clean. They do start to get problematical after 30 years or so but that's way past their design life.

I have seen so many corroded, rusty and unsprung Lucar type connectors over the years. Any connector on a bike will corrode, no matter how it's formed, unless it's protected from the elements.

Any type of connector will corrode if left dry and exposed to the weather. I always assemble mine with silicone grease, and for Lucars solder rather than crimp and use the flexible clear PVC covers.

Some of the multi-pin ones used on modern bikes are a nightmare as the contact surfaces can be tiny.

Just to update this topic, I changed the fuse box to this one fuse box the four way jobbie fits in the same position as the original although I think I intended to purchase the six way.
I still have a voltage drop going on somewhere but with the new fusebox every thing seems to work now

Onwards and upwards to the next issue.......
