V7 Sport Electrics

[SevenSport]

Hi there,

I'm new here, so please forgive me starting a new thread if it has already been covered in detail elsewhere (although that seems unlikely...)

I've got a '73 V7 Sport that I'm trying to tidy up a bit, but I aim to keep it in "used" condition and ride regularly.

One of the few areas that looks a bit sore is where a previous owner has removed the original grey "CEV" fuse-box and fitted some gaudy new item with blade fuses.  I've got the original and I'm trying to rebuild it and reinstall it, without setting the electrical reliability of the bike back 40 years.

Does anyone have any photos of their V7 Sport fusebox showing the layout of the wiring, the fuses and the famous "courtesy light"?  I'd be most grateful if you could share them.

Best regards

S

You might find what you're looking for in the photo album I created of the restoration of a customer's V7 Sport. Start here on page 4:

Inspect your original fuse box to make sure there is no corrosion between the riveted joint of each fuse end clips and corresponding terminals.  Check the continuity and the tightness of the connection as well.  There can be issues with corrosion on those hidden contact surfaces which will significantly impair your electrical system. 

When I first rebuilt my V7 Sport we chased the reason(s) of my poor electrical system function for a long time- new brushes on alternator, regulator, NOS OEM wiring harness and anything else that seemed relevant before it was suggested that I check the riveted connections in an otherwise excellent-appearing original fuse box.  Most connections/contact surfaces that were hidden from view were significantly compromised.  I drilled out the rivets, cleaned the contact surfaces and then reinstalled everything with solder because I had no replacement rivets.  The fuse box is not cosmetically perfect any more but the function now is and my electrical problems on the bike are over.

From my 1974 750S, it will be the same as a V7 Sport

Thanks very much for all your wise words.  I've attached some pictures below of what I'm trying to correct and where I've got to with tidying up the original part.  2 days sat in vinegar seems to have got the terminals looking pretty good again but I note the comments about corrosion between the faces so I'll check continuity is good.  I also note that a couple of the photos show all the rivets being replaced; I have some brass tube rivets on order but maybe pop rivets are going to be a bit more robust.  I also noted that one of the fuseboxes has had the same melt-down as mine....

The courtesy light looks like nothing else I've ever seen so I may have to give up on the idea of replacing that, unless anyone knows of a source?

I will get a photo uploaded when (if) I ever get this back together and working...

Best regards, S

The under seat light was lifted from the Fiat parts bin - used as a glove box light on the 124.

  You may want to keep that little light for originality. I have installed two LED lights under the seat. My source is "SuperBrightLEDs" in Missouri,USA. The part # is P-STRB-1x18. I have a a '73/'74 Sport I bought new in '74. Horst.
