oil pressure and water temp

Post by **cliff** » Wed Apr 04, 2007 8:04 pm

finally got round to connecting up my instruments.

the oil pressure is 50 cold at tick-over and about 35 hot at tick-over, is this reasonable?

the water temp is halfway between normal and hot, is this due to the 88 deg C thermostat i fitted and could i expect the temp to drop to normal with a cooler thermostat?

the ammeter is just in the + most of the time.

I'd be happy with that oil pressure, but I'd also be looking for it to reach 60 or so hot and cold at 2k or higher rpm.

Have you wired the temp through the voltage stabiliser? If not then that might be your problem!

Both sound ok to me - idling oil pressure depends so much on idle speed that it tells nothing - but approx 10 psi per 10 mph in top gear is plenty. Any more is a bonus.

on the back of the regulator there is a short wire going to the fuel gauge, this had a spare 'spade' where it left the regulator so to save breaking into the wire i connected to that.

is this ok?

If it 's on the connection to the fuel gauge - it should be fine.

I did the same but my temp gauge is vibrating as nuts when the fuel indicator reaches his level, .... what do I do wrong?

nothing is wrong, the voltage regulator behind the speedo is not very stable, the gauage should be highly damped to account for this but as the regulator gets older it gets worse. so you may need a new one or replace for solidstate which would be rock steady.

Or maybe add a capacitor to act as a 'damper'.

I tried a capacitor, problem with adding a capacitor is that it will tend to drift upwards towards the battery voltage rather than staying at the 10v its a feature of the mechanical regulator and relativly low ouput load. Regulator turns on, capacitor rapidly charges to battery voltage as regulator has long delay to heat up and turn off.

Its just as cheap to replace the regulator than trying to stabalise the ouput of the old one

Ahhh - indeed - maybe just a small capacitor - but I see the problem. Or perhaps add a 'drain' - just a panel light bulb or similar.
