Missing relay wire on a pcb board relay. Can i still use the scooter ?

[jessejamesw5432]

Missing a loop wire in a pcb board for the relay, i seen some videos of by passing then with a jumper wire possible ? I got the screen to power on off the scooter with a drill battery. New pcb board. New led screen just missing one wire for it to work. Don't want to short anything out. Thank you

Got a new pcb board and in missing the relay wire for the volt converter. I got the led screen powered on off the scooter. Possibly i can use a jump wire but don't want to burn anything out. New pcb board on a yume x11 plus thank you

What is the "relay loop wire" again? Do you have a schematic of this controller? Why is the element missing in the first place?

 

[jessejamesw5432]

Yes. I replaced the pcb board and i lost the 4 pin connector. Loop wire proably not the correct name sorry. Looks like it activates the main relay power converter so i cant power on the scooter. Was going to use a jump wire ( new to scooter wiring ) to power on but don't want to break anything appreciate your help.

Oh, in that case there should be no issue bridging this. Make sure it only activates the relay and doesn't actually carry some significant current - the wire in the picture looks quite thick, but maybe it's because of the connector.

The connector itself looks like a Trident at first glance, but of course it can be virtually anything... if you don't really care, just solder directly to the pins and heatshrink on top.

I’ve read that some might use a thin wire, say a single strand from a 23AWG cat5 Ethernet cable conductor, and use that to bridge the gap. The thinking is that the single strand shouldn’t be able to carry high current and would blow before anything else does. I haven’t tried that though so your mileage may vary.

Funny you say that when i google search the picture Ethernet cable shows up. Thank you for you help . Does it have to be eithernet cable or just a thicker wire ? Thanks agian

Well, the Ethernet cable usually has stranded wire. It’ll have 8, 23 (or24) AWG, conductors and each conductor is made up of multiple strands. One strand is about the thickness of a hair and won’t be able to carry much current (thicker gauge wire could typically carry more current) before burning up. Better that the strand burns up as opposed to other things. I guess just be prepared that the burned up strand doesn’t contact anything else. You could set electrical tape around the surrounding contacts to avoid that possibility.

Ok reallly appreciate your help. Does this mean Ethernet cable is safer to use ? Or should i find the original size wire guage . Im new to pcb boards, i install car stereos. So this is new to me. Should i sotter the jump wire for better contact ? thank u agian .

The Ethernet cable would just be for testing. A single strand from stereo cable would be very similar. You can use that too. I only mentioned testing with this wire because it seemed there was concern of the amount of current flowing between these 2 pins.

But I think you don’t need to test anything since you have already identified the blue jumper that is missing.

That blue jumper you have circled looks like 16 or 18 AWG wire. I wouldn’t solder anything to those pins. I would find out what the name of that plug is and get the female end of that plug. I’m sure there is a kit on eBay or Amazon that you can buy. That plug looks like a molex of some type.

I orderd a bran new display. Bran new controllers and pcb board. I was misisng a relay wire on the pcb board . Yume said they were going to send me a new relay. I just had a video call with them and they siad they sent the wrong relay. I waited 3 weeks from china. Im thinkig maybe its just a external step down converter and i can hard wire it direct to the led power screen. If soneone can help me woukd be very thankful.

 

[jessejamesw5432]

All new parts no power on led. New controllers . Led screen . Pcb board. And they sent the wrong relay. Just want to power it on I don't care if the kights work or amy of the accessories there on a separate battery. Your help would be greatly appreciated.
