Battery Cutoff Switch

[HealeyRick]

The cutoff switch (Lucas original) in my BJ7 will only make an electrical connection if I hit a certain "sweet spot" and not when it's in the "ON" position. Can it be rebuilt? Any tips?

They were not made to be rebuilt but I had the same issues with mine and I just drilled out the rivets and took it apart. There are two copper contacts that get pushed together when you turn the switch and I just "resurfaced" them (i.e. made them smooth and removed the big pits and corrosion) and put in some new rivets and it has worked flawlessly since.

Sometimes you can repair them
:
1 drill out the rivets
2 Carfuly open it up
3 reverse the contacts
4 close it up and add 4/40 screws/nuts to hold the case shut

Now Hope it works---

Thanks for the help guys, I'll give it a try.

Dunno if you're a member of AHCUSA, but Roger Moment did a very thorough write-up on refurbishing cutoff switches a couple years ago.

Thanks, Bob. Member of both AHCUSA and AHCA. I'll check out the website.

one of my first step of my 100/6 Longbridge restoration BUT when I go on the road I have preferred to bypass it--this switch can be critical- now I have the switch directly on the battery pole

Prevention is better!

I think the more you use the switch the better it works. It sort of polishes the contacts. I re-built mine 12 years ago and it still works fine. If you are careful the rivets can continue to be used.
