Hello
I have a bit of an electrical/engine issue which I hope someone on here can shed some light on...
I was driving along when suddenly the engine electrics failed - radio was on & didnt power down but lost all power to the engine - changed down a gear but still losing power so managed to coast car to a parking space in an industrial estate. I mentioned the change down in gear as I dont think it is engine seizure as it didnt lock the wheels up & also didnt slow up as if the engine was seized. The engine will not turn over & I cant hear any click either when turning the key. I have another Puma as a donor car so have swapped over the battery & relays but still no better. I have checked the engine earth strap & gearbox earth & both seem ok. I checked all other wiring I could reach from under the bonnet & found the speedo sensor wiring badly frayed where it enters the sensor housing. All three wires were in bad shape (copper wire showing) & appeared to be touching which would cause them to short out (this may be a red herring though as my other puma runs fine with the speedo sensor unplugged) I swapped the sensor with the good one anyway , but the engine still will not turn over. I have noticed that the air con button light is illuminated as soon as the ignition is switched on & will not turn off when the button is pressed (the light is on even with the heater switched off). Is this another red herring? It just seems strange that the light is on constantly as soon as the ignition is switched on (it wasnt like that before this fault appeared)
I fitted a new clutch a week ago & in my haste I forgot to attach the power cable at the alternator which became apparent after a couple of days as the engine died (lucky I didnt have a fire - I know ) I reattached the cable to the alternator & the car had been running fine for the past week. Have I goosed something up here? Could I have killed the starter somehow? If so, I wouldnt have thought that would have caused the engine to cut out. Could it be the ECU? :?: :? I really am confused here so would really appreciate your help,
Cheers
