Tomtom battery why 3 wires




















I am not but supermod canderson might. He wrote an excellent primer here on replacing the batteries in x20 and x30 models. As well, fellow supermod Mikealder tends to take everything apart as soon as it is out of the box so he may have come across the battery type you are seeking. Look for either of them--or both--or others to respond to this thread over the next day I'll be looking forward to their responses.

I am at a loss as to what to do at this point. Any help would be appreciated. FWIW, I suspect that the two red and two black are in parallel to support additional current vs. It could be since the five wires on the original battery are thinner than the the wires on the 3 wire. I have been tempted to just solder the 5 wire connector to the new battery hooking the two thin red wires to the one thicker red wire on the new battery.

Ditto with the black one. Looking for someone who knows to say this is the way to go. Never seen a 5 wire battery pack in a One XL, I have just checked the two I have in front of me and they are both three pin with three wires, I would get a three wire battery and solder the 5 way plug to it joining both red wires together and both black wires together - Mike.

This unit was given to me by my daughter who bought it used from Ebay. I searched the internet and it would seem like the battery I have F doesn't exist. In case this help, the sticker on the battery says; Type: K1 Battery Cell: Maxell ICP Capacity: mAh Made in China F I started to disect the battery and found out the battery terminals go to a circuit board and all five wires come from the circuit board.

Strange that no one has ever seen another 5 wire Tomtom battery. I wonder where this unit originated from? A prototype of some sort? Truly a mystery which I hope someone here can help me solve. If not, I will be forced to do the soldering trick and hope I don't smoke my unit. Maybe yours is not original, but modified by someone.

This looks like the most likely answer. The third lead is for monitoring the temperature during charging. Yes… some battery has three wired black, red and probably yello … these kind of batteries may be old models….

Battery has 3 wires?! The wires were scavenged from an old USB cable. Next, on the Tomtom board, solder a jumper wire to the lower pad of the D5 rectangle. Reference my previous post in this thread for more info about the D5 location. The red wire was scavenged from an old USB cable. The dark area around the soldered area is flux. The old burned charred diode was removed from the board, then the area was cleaned with acetone prior to soldering.

Make sure you do not bridge the two pads upper and lower in the D5 rectangle together when you solder, you can check that with a multimeter if you are uncertain. After cleaning with acetone you can actually see the board again. Applied clear fingernail polish to the soldered area and the exposed wire to seal the repair. You can now see the silkscreened rectangle on the PCB where the burned zener diode was removed.

The wire is soldered to the lower pad in the silkscreened rectangle. There will be two splices made into the battery wires. The black wire - on the battery will be spliced to the wire soldered to the IN- pad on the TP charger module.

The yellow wire does not get spliced. A plastic rib next to the speaker, where the Bat- pad sits, was removed for clearance. The plastic cuts easily with a knife. You can see where the new red and black wires going to the battery are run along the speaker, they are now spliced to the battery.

Electric tape now covers the battery cable splices as the battery is installed. The cables will be routed through the original wire holder. Those two wires will be connected as the case is closed up. Mine are just twisted together and covered with electric tape. The battery in place, wiring routed, Tomtom plugged in. The battery will charge if the Tomtom is plugged in and will quit charging when fully charged except when the Tomtom is turned on.

When the Tomtom is turned on and plugged in the charger will supply current to the Tomtom and battery, both the battery and TP will be supplying current to the Tomtom. It takes about 2 hours to charge the Tomtom battery when not being used. Guests, see more features - join today! Please login or register. I took the seat off, and there are a lot of wires and stuff under there, no idea what to do now. As far as I can tell, there does not seem to be any 'standard' port or exposed wires to connect this to.

I also suppose connecting this straight to the battery is a bad idea due to the gps drawing power when bike is not powered on. There a little "cigarette plug" to charge devices under the seat, which should be ok for this, but the TomTom comes with the two wires I need to connect. Thx for the help.

If there's some sort of guide, I'll need pics to go with it. Last Edit: December 02, , AM by hansvdc. I answered this in your previous post about mounting the TomTom, but here is a photo showing the spliced wires of the TomTom and the now-removed cigarette adapter the blue butt connectors are the splice.
