    Fixed one electrical problem, now more!

    Okay, so I decided to replace the fuse box on my 97 P38 4.6 after finding two of the BeCM posts on the circuit board had come adrift from the solder joins, causing the usual "Fuses Blown" and other usual warning messages. Prior to this, all earth points had been cleaned, cables from the...

    VERY odd electrical fault '97 P38 4.6 HSE

    Still cant see them. The board isn't bad, apart from the solder joints of two of the BeCM posts, which I will re-solder. I've been following this guide on repairing the fuse box Fuse Box Repairs It's very good

    VERY odd electrical fault '97 P38 4.6 HSE

    Can't see any diodes on the board.

    VERY odd electrical fault '97 P38 4.6 HSE

    Yes, lost over 8l of coolant. Still the temp gauge didn't move off normal. Good point about the connector. I'll check it at the weekend. The board cleans well using alcohol and a Demel with a soft brush bit. I'll check the board with a Mega before I put it all back together.

    VERY odd electrical fault '97 P38 4.6 HSE

    Stripped out the fuse box and dismantled yesterday. I found that the captive bolts for BeCM power are not that 'captive'. Obviously my 'tight' is more than the workshop manual 'tight'. Some evidence of coolant (or something) on the circuit board. I'll give the board a good clean, may add some...

    VERY odd electrical fault '97 P38 4.6 HSE

    I've had battery issues before, and have a good 3 stage charger to keep it topped up. I agree, the fuse faults (which were fine) could point to a low battery. BUT, it was the blower motors running when I removed the key that have got me very puzzled.

    VERY odd electrical fault '97 P38 4.6 HSE

    Having just replaced the coolant expansion tank today (the tube at the bottom for the radiator bled pipe cracked and I lost 90% of my coolant) and bled the system, I then ran the engine to get up to temperature. All was fine, no leaks and steady temp gauge. Switched off to let it cool down...

    BeCM relay 7

    Thanks Wammers. I'll check the fuse box again, and check BeCM connections over the weekend. I'll be delighted if it's not a BeCM relay issue.

    BeCM relay 7

    Sorry, no experience with a RRC. Dodgy electrics can throw up all sorts of issues. Some are easy, some have you chasing your tail.

    BeCM relay 7

    Odd that both blowers, HEVAC and radio display and cigar lighter (I have a radar detector plugged to it) all go off simultaneously, and come back simultaneously moments later. Coincidence three times in a row perhaps? One of the blower relays (7) had failed and I replaced both (7 & 8). Checked...

    BeCM relay 7

    BeCM internal relay RL7 feeds the cigar lighter, radio memory, HEVAC display and blowers via fuses 7, 8. I have had several momentary failures, some so short that there are no fuse error messages, etc. but once I got fuse 7, 8 error messages. Both were fine. I'm told it may be a ageing relay 7...

    BeCM relay 7

    Does anyone know an RS or Farnell order code for a replacement relay 7 for the BeCM in a '97 P38 4.6 HSE? Thanks

    Message Display ageing

    The message display on my 97 P38 is showing signs of age. At night the background is no longer black, but becoming brighter green by the month. I assume this the the LCD getting old. I haven't removed the instrument cluster recently and can't remember the configuration, and before I do I...

    On second thoughts, better take the family. They can help you push!

    What Would You Do?

    Take the Rangie and buy the family train tickets! If you're late for the 'do' just say you took the scenic route! Let us know how the trip went. We'll all be thinking of you!!!!!

    Intermittent A/C

    I totally agree. But removing the dash is not on my list of favourite things to do at the moment. But it's stuck on 'cold' so my point is that it's not the temp flaps moving around on their own. It doesn't go hot, just feels like the A/C goes off.

    Intermittent A/C

    Had it done in March. Didn't make any difference.

    Intermittent A/C

    External temperature stays steady. This is the second HEVAC I've had, and the same thing happened on the original one too. I thought it may be the temperature flaps, but as one is jammed that discounts that theory.
