Genuine Land Rover springs are pretty hard to beat in terms of quality and effectiveness.
The 110 has turned out well, bet you're chuffed. Now time to enjoy it! :clapping:
Series doors are pretty flimsy - I'd definitely not swap Defender ones for them.
The 2005-on all-steel ones with the one-piece pressed frames are the way to go.
New chassis looks like a Richards rather than Marslands? But car is looking good, some nice work there. Nice garage too!
I have galv cappings on my 90, more because I couldn't be bothered to paint them when I swapped them. Plus as it's grey they don't stand out too much. It is also well overdue...
'twas a good shout chaps.
I soldered in the new MJ2955 and gave it a test. Seems to work a dream, I can dial the wire feed from practically nothing all the way up to full speed :)
Thanks again, much appreciated. Can get on with the business of learning to weld now!
Bit of a pain that they didn't design a way of being able to tell which your unit is.
If the case-as-collector is more common, and given your reasoning above, I guess I should go with that one.
Thanks :)
Ah yes, there are a few hits which suggest MJ15015 as an alternative for a BDX18. RS do stock those, although typically they're not in their core range.
The datasheet for the GO Semiconductor MJ15015 that RS supply does show that the collector and the emitter connections are reversed on this...
Would this cause the symptoms described here? Permanent full-speed wire motor?
I can't get a BDX18 from RS, although they do do many similar looking PNP transistors in the same form factor. I can get one on eBay though, so will most likely do that.
Thanks for all the help so far.
Okay, same test but out-of-circuit.
Large Transistor - BDX18: (PNP)
B to E - 603mV
E to B - No continuity
B to C - 603mV
C to B - No continuity
E to C - Full continuity
C to E - Full continuity
The last two results (E>C and C>E) I think show that yes, this transistor is shorted...
Thanks for the reply.
I'm afraid you have exhausted my electronics knowledge. The bridge rectifier, which component is that? The black one next to the BDX18's heatsink?
What element of the power supply would I need to test? It clearly recieves power and distributes it to the motor as the...
Ok, so here are the results of my tests. I've tested the continuity between the terminals, as per the procedure on this website:

First a shot of the board, and the poles of the two transistors labelled up.
B = Base
C = Collector
E =...
Well I can pick up a new BDX18 on eBay for not many pounds, and the other one looks from the pictures like the standard ones I used to play with in school. So hopefully I can get one of those from RS.
Will look for some markings when I get down to the workshop tonight to do my testing :)...
Yes I did.
When disconnected both pots vary from 0 to 10k as I would expect. When connected they both vary from 0 to 6k or thereabouts. Due to another resistance path within the PCB, I can only assume.
This leads me to believe the pots are OK.
I will test those out tomorrow, thank you...
Wozzaaah,
Thanks for that, simplifies things a bit :)
If there are any ideas from those on here I will gladly try them out before sending it off to Murex. As you say, that will be unlikely to be cheap.
I'm no expert, but I can solder and I know enough about the basics of electronics to...
Hmm
I changed the pot on mine and it made no difference, same readings and behaviour as before.
I'm gonna have to take the PCB to my local Murex agent and get it sent away for testing I think :(
Sorry to jump in on your thread joss.
Obligatory first post :whistle:
I have also recently obtained a Murex Miget, and the only problem I can seem to find with it is that the wire feed pot. seems to have no effect on the wire speed.
Will remove the controller board this evening and have...
