  1. To my eye that looks like the ignition lock unit without the switch. Search the SJ website for ignition switch and you will see a matching shape. Cheers
  2. Sidebar question for the members - what does it take to remove the knob? Mine seems locked to the stick, all reasonable measures of torque so far have failed to budge the thing.
  3. The Haltech I've picked generates a square wave of either 8 or 12v amplitude, with number of pulses per 720 degree cycle user specified. Turns out Haltech offer a Tachometer Output Adapter which should resolve the matter if needed. Cheers
  4. Thanks Thomas, you're golden! BTW, I was asked to check voltage stabiliser output for the tech and despite advice from others in the community it seems to dither around 5.7 - 5.8 VDC. Does this seem correct?
  5. Spoke with instruments technician regarding freshening up the Smiths units native to my S2, seems there may be an issue with function of the tach due to change from distributor to crank-fired ignition. The Haltech ECU I expect to use provides a square wave signal which the technician worries will not drive the tach. He's had no success in fettling a mate's Elan tach for use with electronic points converted distributor, thinks we might do well to source modern workings to fit into the OEM Smiths tach casing. Suggestions?
  6. There is an upgrade known to improve on the input shaft needle bearing/circlip business - machine to fit a roller bearing. FWIW. Cheers
  7. The overview "guiding" this madness revolves around concern for undiminished power being available for headlamps, rad fans, cabin fans up front, various presently unconfirmed pieces back in the engine bay. My lighting guru has detailed the imperative of halogens operating at design voltage, what I've done further reflects intent for optimal performance ( relays/ fat wires for the windows motors ) and reliable service ( blade type fuse blocks, marine grade earthing busses, new wire in ample gauge. Attached images show common buss fuse block in the boot, 2 x 10 gauge feeds from a Mega/Midi distribution fuse block in aft bay near battery, backside of 8 fuse block for placement in the glove box, underside of a 7 mini relay block placed just inboard of the LHS headlamp pod.
  8. Regarding line pressures, given equal bore sizes in both ends of the M/C one will see equal pressures for both front and rear circuits. Where braking balance is concerned, a differential is created when calipers of differing bore sizes fore/aft result in differing clamping force for a given line pressure. Further biasing on Esprit is created via differing rotor and tyre diameters, fore/aft. Cheers
  9. What to expect in removal of the knob? The one off my S2 seems unwilling to part company with the stick.
  10. Yes, I've dared to take a photo or three, painful eyesore to the sound of mind I'm sure! Look for those late tomorrow, not handy at the moment. Cheers
  11. Well done, Dave! Those tanks are ghastly indeed. Cheers
  12. Update/confession, Summer 2021. Well into the wiring updates enterprise, thought it appropriate to report in on my state of chronic Shipwright's disease, suspicions looming that Mad King Ludwig of Bavaria must have dipped a toe in the Lipp family gene pool back in the day. In essence I seem to have rewired much of the car with relay and fuse blocks, high spec earthing busses, and current OEM spec cross-linked polyethylene insulated wire of higher gauge everywhere other than portions of the instruments binnacle. It's becoming a thing of aesthetic and technical beauty, at quite some cost in marine grade parts, but Lord does it take time! Cheers
  13. Chrome-moly is highly unlikely for use in production automobile frames, requires heat treatment after welding due to the alloys that distinguish it from mild steel. UTS above that of MS may permit spec of lighter gauge tubing when heat treated throughout, making CrMo desirable for competition cars and aircraft. Amateur race regs ( SCCA, eg. ) in North America prohibit use of CrMo in roll cage structures so as to eliminate vagaries in outcome after welding. Cheers
  14. Let's see if I can help. _Manual - S1 and S2 Workshop Manual.pdf
