Ammeter Problems??

[tiggyfudge]

Hi all. I`ve just begun life with a TVR s2 series and am loving every minute of it!! I have one query though.... After starting up, my alternator dosn`t kick in and start showing 14-15 volts on the ammeter untill I have either driven for about 5 miles or I floor the it (Not wise after just starting up eh?!) ! This has me really puzzled. Any suggestions to the problem?

It wont kick in until you have hit 2k revs

You dont have to keep it above 2k but it needs to see 2k

Just blip the throttle so the light goes out. BTW, if the water temperature increases when you switch on the lights and/or heater fan, then the earth points need cleaning. Always a good thing to do with a S!

My water temp increases with switching on lights etc it even rises when the fan cuts in

welcome by the way

my instruments are all over the place depending what's switched on or not. If the fan cuts in while the lights are on, the rev counter goes up by about 2000 revs (the engine doesn't speed up, the counter says it does)

I try not to worry about it. Successfully.

The voltage funnies can also be caused by a drop on the main switched ignition feed, often caused by poor contact at the main connector to the ignition switch. Worth feel the temperature at this connector with everything turned on just to make sure you don't have a potential melt-down on your hands. On mine I had several small voltage drops across the ignition switch itself, this connector, the immobilizer, the fuse and so on adding up to about two volts with everything on. That is far too much for comfort. My solution was to redirect this feed through a 40A relay straight off the main power terminal so everything sees full voltage - not elegant but it works!
