Hi All,
As well as the fuse box and relay kit there was another goodie from Bits4Brits, a voltage regulator.
This is used to convert the twelve (and a bit) volts into a "stable" 10 volts for the Temperature and Fuel gauges. The original unit works of a coil of wire heating up and working a bi-metal strip creating a sort of on-off around 10V, not very good originally and after 40 years even worse.
Only problem is that the new unit is a modern IC and whilst it is still buried under the dash I wanted to still try and replicate the original so time for a bit of "adjusting".
This is the original unit.
The internals out and you can see the wire windings.
This is the new unit, not so period looking.
So time for a bit of surgery.
Good earth is important so the IC was pop riveted into the case.
Routed the cables out and crimped on new spades.
Job done !
I think it looks a lot better.
As always, any comments, questions or abuse welcome.
Cheers,
Richard B.

Hi Mike,
ReplyDeleteSorry I'm in Dubai very few MG's out here at all and not heard of any in Qatar. A lot more old yank muscle if that takes your fancy.
