Rev counter is dodgy connection on the back of the alternator. Simply pull off the female spade connector clean the male and squeeze the female a little tighter with some pliers and reconnect, all should be well
Cheers,rev counter now working
Blanked off the egr today and one of the front windows started playing up so I'm going to strip and clean the switch.
Also the handbrake light keeps going on and off,what should I check first?
Cheers
