Hi i am new to the club having recently been lucky enough to win a Spitfire 4 in an online raffle, (yes really), I own 2 other Triumphs which are slightly more modern (Stag and Dolomite Sprint), so i am still getting used to the basic charms of the little Spit. The car does appear to have been uprated slightly at some point in its life having lost its original engine and (colour scheme) and is now running a 1300 engine presumably from a mk3 Spitfire, i have a couple of small issues that i want to sort out. There is a slight squeal from the left hand front brakes when they get warm whilst breaking. I have not manged to look at this yet but would i be right in assuming that the brakes would have been upgraded at the same time as the engine ? or were mk1, mk2 and mk3 spits all the same in the break department and if not how can i tell what i have ? by looking at them. The other issue is the temperature gauge does not function correctly, it just keeps rising to HOT as soon as the car is started, although the car seems to be running and driving fine,(I have swapped out the temperature sender) the fuel gauge seems to work okay, the car appears to have been altered from the original positive earth to a more modern negative earth configuration. I suspect that either the Voltage Stabiliser is incorrect or wired up wrong, or there is a fault with the temp gauge, can anyone tell me how the VS should be wired up for a negative earth set up ?. Do temperature gauges go faulty ?(I have never experienced this.)
