I'm sure you are all trying to help, but the original post is from 5 years ago.

At the risk of trying to get blood from a stone, can you elaborate on what's missing, and what's remaining? At minimum you need a battery (two wires at the top), motor (three thick wires, a number of smaller ones marked hall effect) and a throttle (three small wires)

Why can't you just plug it all back in as it was?

You should be able to see which one is blown. If in doubt, use your meter to test. Select 200 ohm range (on yours, about 7-o-clock). First, observe display with test leads not connected (infinity). Then observe reading when test leads touched together. You should get close to 0 ohm. Take the...

I'll bet you do.

Yup, you should have moved toward the center of the road.

You need to test the charger.......

No need. If it's a 36v battery, and its only getting to 32v, then either it or the charger are faulty. Next check the output voltage of the charger.

Cheapest I can see is £269 + £15.50 delivery. That's discount price for JB owners....

What makes you think a new battery is £150 ?

Until recently, I was all e-bike. My neighbour wanted me to convert his bike, and duly presented me with an ancient MTB. It wasn't suitable, and I said I could source something better from E-bay for £30, given a few weeks. Next day a GT Arrowhead turned up locally. I won it for £30 because it...

I've been running 2.3 inch tyres (schwalbe Fat Frank, equivalent to Big Apple) for a few years on my e-bike, and I wouldn't swap them for anything else. They are extremely comfortable, low rolling resistance, and puncture resistant (over 2000 country miles) and have loads of grip for tarmac use...

...but beware, as in everything there are some truly awfull V-brakes out there. A friend asked me to look at the brakes on his B.S.O the other day. I was shocked to discover the arms were made of plastic. Bendy, cheap plastic at that. As were the levers, and even the crank arms. As Flecc says...

Ah, that'll be your problem then. Yes, it will need to be switched on to test it. Running it down by running 'no load' as you are doing could take a long time. Many hours if the battery is good. (maybe 10 or more)

My friends (elderly and slightly eccentric) father drives around in an ancient 2 sester british sports car. I could be wrong, but I think its pre-war.

I agree, rim brakes are fine for most people. I'm heavy (100k plus) and I ride in a 'spirited' manner. Decent v-brakes are enough for me.

Ex-sealant!

Unlikely, but it won't damage anything. I think you'll have to bite the bullet and send it back. If you ordered correctly, and the fault was the sellers then I guess you should be entitled to refund of the postage cost.

You might have to leave it a few days, then re-test

That indicates a battery problem. It should be closer to 42v. It's either a duff cell, or its out of balance. It might be worth leaving connected to the charger for a long time, to see if it will balance out. Long shot. It may be possible to manually balance it, but that's probably beyond your...
