  • Pel job 25.4 puma & stop solenoid

    Hi all,
    1996 model that has been a wonderful asset around our 20 acres, which it never leaves.
    So glad and grateful to discover this forum and in particular the list of puma fault codes. Confirmed what was becoming obvious - a fault with the stop solenoid.
    Just buy a new one, easily sorted. Nope, no difference. Checked fuse, relays and wiring as far as my limited electrical abilities go.. No joy.
    Off down to the local emporium and sourced a brass stop-off fitting with the same thread. Hole drilled, bit of brass tube soldered in with nut and bolt through with a spring on the outside between the bolt head and fitting. Hey presto, manual stop solenoid. Got used to the minor pain of having to lift the bonnet to stop it. Wish I could find and cut the wire to the friggin beeper.
    It has a few other little foibles, but still does sterling duty.
    Must admit my one concern when we bought it was that it had a brain. I have a lot of sympathy with the great Barry Sheene’s dictum when asked about going on a horse “ I won’t ride anything that’s got a brain of its own.”
    We also have an ancient Komatsu FD20 forklift, saved from the scrap heap and renovated by our wonderful local engineer. When he handed it over he said, “I’ve ripped out all of the electrics except the heater plugs and starter, that’s all you need.” No problems on that side in 20 years.

    Welcome Keethy ..sounds like youve had your troubles like the rest of us ! At least you got a work around .. and glad to be of service..... Perhaps you missed a point Ive made before that the puma system of that era relies heavily on various earth points all over the machine, think theres about 5 or 6 and a main one inside the cab. If any or some of them are poor, the units throw up error codes and fault for no reason. But of course if its been lobotomised, that wont be an issue

      Muz , Lack of wiring was on the forklift , not the excavator

          A more determined search of the earth points is in order when I get a minute. Thanks for the input!

            And my 1963 David Brown 880 (rare 4 cylinder) doesn’t even have heater plugs and still starts first time. Charging system hasn’t worked for 30 years. Rotate the trickle charger.
