Yes but they would not solder in very well on the old boards I don't really have the tools and skills to do the tiny joints even under my magnifying glass. Very fiddly

The flipping thing won't work and I even added another mosfet which was very fiddly with the solder not sticking. Absolutely sick of it and to me the controller is scrap now. I've ordered a more simple cheap Chinese 24v 500w controller with its own throttle to try but not confident as they say...

Finally got the MOSFET and soldered it in and its fixed! It was a fiddly job so I didn't take any others out as wasn't sure each was the same anyway. I ran it about 5 miles and it seems ok but pas stopped working but I may have missed the plug. Just as I got home I tried it from stand still and...

Yes restored a G15 but now a G4. Ebike is just a bit of fun but still waiting for the mosfets.

Yes I've run and restored 6 Ginetta's now plus various motorcycles so interested in all mechanical things. I got the bike to play with and learn from before I move on to something better and faster.

I've not noticed any sensors but will check. I have noticed a pair of soldered bars on he controller and wondered if they set up a resistance?

So what governs the speed cutting off the power as I ride faster?

Mines a brushed motor controller I think?

Ok thanks I'll order some.

Also can I ask about how the controller works? My twist throttle does not seem to have much in the way of speed control as it almost just on or off power wise? Should it have a number of incremental speeds from a slow start? The power did cut off once it reaches a speed possibly 15mph but what...

Yes I found those but questioned the specs 110A 55v 200w as the other numbers printed on them are not the same? The supplier had no idea! I'll buy them and see I guess? Looks like P608k Y1 K2 but don't know what the numbers mean? I wondered if there were a selection of specs for the same shape...

Iffy MOSFET out but no idea what spec it is or what the numbers mean on it? This one does seem to have continuity between all 3 legs?

Any ideas before I desolder the mosfet and try and search for a replacement?

I have a thick black and red set of wires going in + - and a thick green and blue wire coming out so presume these are for the dc motor? Testing with probe in red+ I get continuity beep going to the blue wire but only get a quick quiet chirp from the green? Picture shows my meter and wires.

My meter is not digital but on continuity testing on the 3 legs of each mosfet with positive in the battery + connection one does beep on all 3 whereas all the others will make a quiet chirp on one leg? Yes I know it's maybe not the correct way to test. One cap has sticky stuff on top. More...

All the testers seem to be for brushless motors?

Excellent and something completely new to me to try in lockdown! I don't really understand the testing but I have a multimeter to try. I've looked on eBay for a replacement controller but haven't found anything that looks similar so I've no idea which would work? Most seem to be less than 35...

Inside the controller I found a treacle like substance in places on the pub so I cleaned it off but otherwise all looks well. Caps don't look blown. I'm not sure how to test the 4 mosfets? Do they stop the power going to the motor on switch on? I don't know how the controllers work really. I'll...

Thanks Still does it with brake connections disconnected. Something in the system should hold off the power when the rocker switch is turned on? Before it made a small jolt but not enough to shoot off? Inside the controller is what looks like a black relay box? Could the switch circuit to the...
