Hello, fellow youtubers. Everyone on Facebook in this clip, again, with bobby modify. This clip is an electric bicycle, forty-eight volts. Ah, this one is, Turn on the ignition and the light will turn on. The dial doesn't light up. It's still. open and closed type. I'll try it out. There This one is plugged in. Friends, friends. Already plugged into the house power socket. Ah, I'll plug in the cable. Ah, plugged in the charger. Turn on the ignition switch. The I will leave this one open, my friend, and then remove it. Unplug the charger and the battery goes off. Turning on the ignition, the light doesn't come on. , but plugged in Then turn on the ignition switch. When I disconnect the cable, the ignition switch light that is left on is off. This symptom will come soon. Let's go together. First of all, , we're here. It's easy, it's easy. You have to have it. Set it up. Go to the area to measure the continuity of the wires. Because we will here, let's it is. Is it missing? Ah, there is a sound indicating that the fuse has not blown. My friend, After that, let's chase the batteries one by one. problem with the battery? Set the measuring area to measure the direct current. Ah, measure one ball at a time first. Friends, ah, the first ball, Twelve volts, second one. Twelve volts, ah, third one. Ah, is there a more than ten volts. It's still there, no problem. The fourth one is more than twelve volts. Ah, that means there are four batteries. no problem. It still works. When we came to measure it, it was four batteries. Does it have a light? If it's four batteries like this. Let's look at the two wires, the black and red wires, Ah, go raise the box. Power to power the box This is the black wire. We dipped in. The red wire here we dunk. The four batteries won't come out, my friend. It's normal. Batteries. must have approximately forty-eight volts, but this one doesn't have volts. What happens is easy, because it's Just now, we measured every battery. Ah, it's not lower than ten volts. Let's see. Let's see. From the first one, ah look at the wires first. Is there a tear or not? Or should I measure to see which battery cable? that is not continuous We can measure it. Set it to measure the direct current as usual. Ah, let's measure the batteries one at a time. Ah, but the take the negative terminal and poke it at the battery, this black wire. Twelve volts. And this black wire is attached to this battery. We come to measure the positive terminal of the next battery. Ah, Twelve plus twelve equals four volts. And then go to the next one. Because the black line It's attached to another battery. normal. It must be, ah, thirty-six. If it's the third child, But this one is up to minus twelve. It seems abnormal. we'll come and see what's causing it. The battery shouldn't have a problem. Because it's ten temples. We measured the voltage and it was ten volts. shouldn't be any problem. I think I've found it. Friends, read this, have you seen it? I'll zoom in and see. Here, the cable is broken. this is a protrusion coming out. I'll try plugging it in. Oh wow, wow, break the plug, my friend. The wire is broken, friend. Oh, wait just a moment. Let me measure how many batteries together first. Ah, here it is, forty-seven. The seven-volt point is almost forty-eight, which is considered within the standard range. There's no problem. The cause is from the battery wires. From one of the batteries, Another one is broken, causing the key switch light not to come on. In this case the fuse didn't blow. Ah, here we are, the battery terminals. If it's a battery with unsoldered terminals like me, It's a terminal that is like tightening a knot. There will be more problems than with soldering. Because there is salt and dirt stains. When it gets wet with anything, there will be a problem with the battery terminals. Try. And then the battery terminals first. First, before moving on to other points, Ah, let's turn on the switch first. This one will probably need to be soldered completely. The work can now be completed. . Now let's try turning on the ignition switch. I haven't done a Chinese budget yet. Just touch the battery terminals. Ah, it's already connected. The cable can't. Here's the cable. I haven't plugged it in yet. Ah, it's stuck. I'll try plugging in the charger cable. let's see if the light The green color that is stuck. Will it turn red? Here, Before plugging in, it will be green, friends. Because I still don't have the battery. When we plug it in If the battery is not full, it will show red, my friend. Five. Ah, now the fan is working. It's like this. Friends, for this clip, ah Hopefully it will be very useful to friends who are facing problems with electric bicycles. key won't turn on. You can follow the clip. friends, for this clip, I'd like to say goodbye for now. See you in the next clip. Thank you. Hello.
