>Similarly, pay close attention to the engine oil level. I don't
recall how my '80 Spitfire is wired originally, but on my '70 GT6
(not that far off from your Spitfire) if I pull the wire off the PDWA
my oil pressure light no longer works too. (It's wired so that low
oil pressure will make the bright red brake light come on too, but
what the hey, if they were that worried about someone not seeing the
little green oil light<
Interesting. On a TR6 it si quite the other way around. The oil pressure
switch will trun on both the low oil light and the brake warning light but
they will be dim since they are wired in series. But if the PDWA switches
closed the Brake Fail light will come on brightly but the oil pressure
light will be bypassed by the PDWA and will no longer function. But if you
pull the wire from the PDWA it will revert to the former situation where
both lights will respond to the oil pressure switch.
It's odd that two cars from the same company of a similar vintage would be
so divergent.
