Can anyone help me please I have a lima king loco, tender drive. The pin that joins the loco to the tender is missing and it looks like someone has been messing around with the wiring, I have tested the tender motor and it races so no problem there. Is there any way I can connect the loco pickups without messing about with the metal bar that joins the two units, it's doing my brain in.
I've tried using a steel screw/bolt but no luck. I've taken some pictures so if anyone can see a problem please help.
the last pic shows the wheels at full power but nothing happen

The pick up wipers on the loco wheels are the same side as the wipers on the tender wheels, so these can be connected by a wire, and should have a connection to one motor brush. Avoid any contact with the loco chassis, see next.

That suggests to me that the pick up from the other rail must be through uninsulated wheels via the axles running in a metal chassis block. The copper patch around what I take to be a screw hole at the rear of the loco, should in some way make a connection to the motor brush that isn't connected to the wipers. Probably intended to be linked to the tender by a metal drawbar possibly with a spring to make contact to the copper patch, and then wired onward to the brush; but I have no clue to the detail of the original arrangement, and cannot find a diagram online to help. (Tried Lendons usually useful lists, but no joy.)

My memory may be failing me here, but I seem to recall that my Lima King had pickup on one side on the tender and pickup on the other side on the loco. A single connection between the loco and tender made the circuit.
I'd be inclined to sling a single flexible wire across.

Thanks for the info, I'll try that tomorrow
Could be resolved by running wire of suitable flexibility and length between the front most motor terminal and the contact strip to the locos driving wheels.
I lost the info about the track when I got to 9 ?????

Thanks for the info, I'll have a play with this info tomorrow and see if I can get the dammed thing running, cheers

That's a fit with the 'mucked around' appearance of the loco, that 'Trainman' commented on in the opening post..The pick up wipers, dangling wire, and could that copper coloured strip with two holes possibly be the original loco to tender drawbar? ; something wrong there whatever...

Never having looked at one of these models, that's why I went looking for a diagram to see if that clarified matters, but no joy. Anyone got one?

I had a look at a loco for sale on eBay showing the undersides

The photos showed the drawer bar connection, but not very clearly
I have spent 4.5 hours this morning trying to get it going with all your suggestions, thank you everyone for your help, I'm about to sling it in the bin as at this rate I'll have no hair left to pull out.
I think the only other option is to let someone who knows what they are doing, fix it for me. I'm not good with electrics.
Can anyone recommend a good repairer please as I'm not too well at the moment and this isn't helping with my recovery.
Thanks everyone for your help and advice 🙏

Whereabouts are you in the UK? If you are in Hertfordshire, KS models in Old Stevenage would be my recommendation.

Thanks for your reply, I'm in Worcestershire, I've been debating whether it's worth getting it repaired as the cost maybee more than the loco is worth. Or I can weather it to a scrapyard line state and sell as a non runner

Check the tender wheels that pick up current, the two outer ones without traction tyres, are making proper contact with the contact strips and if so test the motor again with one wire to one of the wheels and the other to the front motor terminal. If the motor runs okay then the issue is a lack of connection to the driving wheels with the contact strips to them on the loco.

I'll put a pic on in a few minutes, I have managed to get the thing to run by soldering a wire to the rear terminal on the tender and touching the loco wheels that have no other connections, it only runs when I touch one of those wheels?????

I have attached a wire to the front connecter and if I touch the loco wheels on the side with no copper contacts, the train runs OK, see pics, I need some way of connecting the wire

The pics posted in the OP are exactly how my Lima King was and it wasn't 'mucked around with'.
Lima specialised in pickups on opposite sides at opposite ends.
In the case of the King, there were only pickups on one side on the loco per the pic just above this reply. Power from this was passed through the coupling to the tender exactly as shown in the pic above, complete with the 'spring wire'. There was a connection on the tender with a wire to one pole of the motor. The other motor pole was connected via wire to pickups on the backs of the wheels on the non-traction tyre side of the tender.

Around 1993, I extensively rebuilt my Lima King. I no longer have the loco chassis as I replaced it with a Comet chassis and replaced the tender with a Dapol (by this time, still an Airfix model) motorised Castle tender. Being 5 pole, the Dapol motor ran far better than the 3 pole in the Lima. This model loco is still sitting in my showcase right now! It hasn't run for over 20 years as I never converted it to DCC. Must put a decoder in it and give it a run.

TBH, faced with the same situation today, I wouldn't bother with the Lima King. The current Hornby model is infinitely better. At the time I did my Lima King, the Lima model was actually the better (more accurate) of the two as the Hornby of the time had vastly incorrect axle wheelbase and we less detailed.

Going back to your wiring, what is in the pick looks OK to me. You need to find a way to attach pickups to the chassis to run on the backs of the wheels - good luck with that as no glues stick to Lima plastic! You need to screw things into the plastic. And it is pretty touch stuff.

Thanks for all your info. It's pouring with rain today so I'll have plenty of time to somehow find a way to sort out a connection
Thanks again

Success, all sorted, managed to get a good connection also changed the tyres, it runs now better than it ever did, so thank you all for helping me sort it out
