Re: SW20 Tachometer and Boost gauge sender unit.
I fixed the tacho a couple of weeks ago. Started to read lower and lower until it almost didn’t move at all.
Need two 10uF caps (I bought bigger voltage ones, 50or 60v - plenty of room to fit larger ones), they are about 10-20 cents each. Quite an investment.... :). They looked fine btw, didn’t display bulging or leaking. Easy to do if you are handy with soldering iron.
While cluster was out I inserted some LED globes I had (eBay spec). Reading the requirements for needing to sand the back of dials etc I thought I would just give it a go and it has transformed the dials. Looks fantastic and like a modern car.
