Hi
I've a 1999 ford transit motorhome, recently it's playing up on the start up..when ignition turned on, the dash lights come on as normal apart from the red engine light...which flicker's not able to crank engine, then after a few goes the light stays bright and it fires up....sorry, it's a diesel 2-5......
I'm guys bad earth.....


Thanks
Alan
