Thread: Ignition cuts out when brake pedal pressed

Range Rover Mark II / P38

Post your results here and we will help interpret them for you

Hi all, just a quick update. I've checked the charging system; Alternator output at 2000 rpm is 14.4 volts no load. Across battery terminals; 14.38 no load and 13.8 with full load. I'm still to attribute the loses to the various leads etc but its only 200 milli volts in total. Battery voltage after load test is 12.59 volts. All in all, it seems ok here.

Rupert has zeroed in on the BeCM and I kinda agree my problem does lie within this mischievous piece of English electronic engineering. He suggested I remove it for inspection...which I am about to do.

Sigh, am I crazy or is this a perfectly good way to spend a lovely winter afternoon? Nope, there is no joy like one receives after successfully mastering a mystery, nor can any other car fill one with such contentment whilst purring through the country. On the other hand, I could be crazy.

Regards,

Lani

You haven't been called in to look at the blinged up P38 sitting at the Metro servo on Bexley Rd ?
I noticed it while filling up & wandered over for a look. On the dash was a few engine wiring schematic pages .

Okay, the sun's gone done, I've a beer in my hand...and the problem is solved.

Okay, the sun's gone done, I've a beer in my hand...and the problem is solved. The trouble lay not so much in the BeCM, but more so on it. Took the seat trim off, removed the seat and started undoing the BeCM. Began undoing one of its earth connections and guess what? It was already loose!

Full kudos to Gary and Steve, you both suggested checking the earths. Thank you. Thank you also to everyone else who offered some insight, it was most appreciated.

Great work, I'll join you in celebrating (well, I began earlier than you I do believe).

Awesome!

Good find goldiloxgirl and a great result. Is still has me stumped how they can come loose after close on 20 years of being untouched.

Don't you love it when you start expecting the worst and it turns out to be such a little thing. Had a few of those, not that I am paranoid about the P38 ha ha
