The Jaguar instructions appear to limit Specialist Equipment to the use of a sensitive voltmeter and a robust ammeter, which are infinitely simpler to use than all the complicated stuff you, David, get up to with your programming stuff ! OK, the sparks may be more complicated but only because they'r...

RB340 Voltage Regulator adjustment - for Rookies.

EDIT : This thread didn't get very far when I started it. However, if you now scroll down to December 2013 you ought to find my informed conclusions. The only tricky equipment you need is a big ammeter (£15 off Ebay for something good enough to have used on a Calder Hall nuclear reactor panel when ...

Starter motor is standard, was NOS in 1990 and only done 7.000m since so I was hoping it would last a while yet. Heater motor should be black, should it ? Could have done it recently since had the coils re-wound ............... My car's actually 1963, must change my listed spec, does that make any d...

Disguising a modern battery inside an old-case

My last old-style battery lasted 5 years but ended up spewing acid during hard-cornering through leaks in the pitch/resin w.h.y. seals around the tops of the cells. Once the battery had been rinsed out copiously, I used a sharp tenon saw for the lobotomy, along a suitable seam, and completed removin...

Dave, Did you get longer SS nuts (my brass/bronze ones seem 50% deeper than a normal standard nut) or just use stock ones ?

David, can you update us on your subsequent experiences with nuts and washers in the manifold-to-exhaust-pipe solution ? I lost 2 or 3 brass nuts on a run to Barcelona in December, despite having tightened them up shortly beforehand, and yet I must have done 5000+ miles with the same nuts undisturbe...

WD40 was used to lubricate the hone, and then the whole lot degreased before assembly with the correct red grease ........... personally I wouldn't put WD40 anywhere near a hydraulic seal.

Peter, Like all of an Englishman's problems, all it took was a cup of tea. Followed by a mandrel made from a bit of split 16mm electrical conduit in the 3-jaw, a high speed, 400 then 600 then 800 then 1200 wet+dry lubricated with WD40 wrapped around it, finished off with a dab of Solvol Autosol .......

Peter, They are in apparently perfect nick and have functioned fine for the last 10 years, I am only changing the seals because I had them in bits whilst working on the pedal box ; the pitting on the cupped-end isn't very pretty but they always seem to go rusty there, probably because people don't l...

The effort required of the quadrant and the linkages when operated by hand under the bonnet (and disconnected from the pedal and its spring) seems out of all proportion to the effort necessary to control the butterflies.
