Tri-ang Hornby Romford Wheels conversion. Assistance please.

A while ago i mentioned that I was converting an old Tri-ang Hornby Loco (a Class E2) to be fitted with Romford wheels to run better on my layout. After looking at a few posts here I got a rough idea as to how the conversion is done.
Simply take the wheels off the model and take the axles out with the aid of a wheel/gear puller. Some new wheels and axles were bought and were fitted on. Some fibre washers were added to areas to prevent any shorts from the wheels touching the chassis block.
But when the model went through testing something went wrong. Somehow a short has developed and theres no way of knowing what has caused it or what went wrong during the conversion.
Would anyone here know where I went wrong, please? Thank you.
The type of chassis that is being converted is the one with the X03 motor geared to the front axle with slotted prong pick ups on the right hand side.

Not trying to be condescending but, have you got both wheel sets the same way round (insulated wheels on the same side)? I've made that mistake before.

That was going to be my first thought as well.
Seems the most obvious if all was OK before!

have you limited sideplay. I had the same problem with a B12, resolved by using crankpin washers as the rods kept touching wheel rims and shorting out. Take the rods off and see if it runs .

 

Other than that Mixing up the wheels  which is not difficult to do and with newer Romfords its not easy to tell insulated from uninsulated

Well the idea that I thought was how it was done was having the pick up side with insulated wheels and the other with live ones. 

Could this be it? The side rods haven't ben fitted yet so it can't be them.

Right, I think I've found the problem. Turns out that the motor has failed so I'll have to get another one ordered to replace this one so that I can carry out the test again.

This one has been giving me some troubles for sometime but I'll keep it incase it can be salvaged at some point but for now I'll sort out a spare one.
