Rider 400 not charging on bike mount despite power

Connected bike mount for first time from switched live (Horn supply)
I have 12v at all connections up to mounting plate, and 5v between brass charging pins - but tomtom unit does not charge up. Battery sign stays on with bar showing rather than lightning bolt.
Have tried wobbling it around and changing from landscape to portrait poistion but no improvement.
I see on this forum that a faulty mount is not uncommon - anything I can do to test it?

    One of the worst things you can do to a Lithium battery is to run it flat so at a certain percentage of discharge (Unspecified)... The device will go into 'Power Saving Mode' the screen will dull, and the device will eventually turn itself off (Not Sleep)

    There is a Battery Status display available on the devices Status Screen
    Press and hold the on/off button until you hear a drum-roll sound Continue to hold the on/off button until the Black & White Status screen is shown.....

    If you are worrying about the device charging, you might consider one of these gadgets

    b23e2fef-ffbf-4127-80b0-646533d6f987.jpg Simply plug the device into the USB socket and plug your lead into the USB Doctor, the device will display the Voltage and Power being used by your various USB devices
    I have one of each type they're only peanuts to buy, search Amazon/eBay for USB Doctor

    Battery has never been fully discharged
    The battery signs change when on mains charging lead ie; lightning sign - but not in the bike cradle despite power at the 2 brass connections (5V)
    Have checked the status = 96%

    Hi

    As you have tested the output between the two brass pins and that is 5V, then the mount is working. If you ride for a while is the device discharging? ( Could it be the display is not changing but it is still receiving power) Is it possible you are not getting enough power (Amps) to the mount? some older bikes can struggle a little. Are you able to test your device on a mates mount? Have you contacted tomtom support?

    Tried on a ride today for 2 hours - with a partially discharged battery.
    No evidence of charging - will contact customer services as this is not acceptable

    I am experiencing the same problem with my Rider 400. My charging cradle is showing 5v between the two brass pins. But the device fails showing low battery warning and shuts down. It works fine via USB connection in my car.
    Any ideas please?

    I had the same problem, even though it was showing 5v at the mount pins, after looking around i found a post stating its due to the weak springs that push the pins into contact with the satnav. I wasnt prepared to pay £50 for a new mount that will just fail again, so i just use a powerpack. With a fully charged battery and full powerpack ive done 12 hours rides no problem. I've also got a usb charger cable wired to the battery if i need to charge the powerpack up on the go.

    Hi
    @Rommel1200

    I used a 5200 mAh Battery Power pack from one of the Aldi Thursday Sales....
    Last year I drove from Worcestershire to the British MotoGP Silverstone and back using GO 520 and a 5200 mAh Power Bank
    The Power Bank has 4 LEDs indicating charge state only one LED had turned off on the Powerbank (I guess minus 25%)

    Just checked and the GO 520 says Worcestershire to Silverstone 70 miles... 1 Hour 24 minutes (3 hours return)

    There's a Micro USB port on the back of the Rider 4xx/5xx under a rubber bung, If your thinking of using using this port it would leave the device open to the elements, water ingress and a dead device

    Hi. I have problem with mount, it is not charging. But my charging cradle is showing not 5.54V, but 12V. Do you think that any electronic inside in the mount is dead ??
    And why it happened... Wires I connected directly to the battery. It was working 6 monts maybe

    12V is not good. The electronic inside in the mount must be defective.

    Do not connect your Rider it will probably will be destroyed.

    @vllado20

    Wow those connections on the Rider Mount are well Cooked
    looks like there was dead short across the terminals :o
    Do you have a in-line fuse in the circuit ???

    Hi . They are not burned. I tried to make them bigger to make bigger contact place :) , of course I tried it after my mount was dead .
    My rider 420 is working perfekt.
    And today a have fix everything. I soldered plus and minus wires directly to pins from inside. You can see on the picture.
    And I used 12V socket and usb reduction so I have 5V now. Everything is workig perfect. And of cource there is fuse as well :) .
    I am plannig to replace 12v socket for smaller later.
    But thank you guys with help ;)

    Hi
    @vllado20

    Necessary is the mother of invention ;)
    Like you, under seat on my Yamaha Fazer 600 I use a car power socket on a short fly lead connected direct to the battery, the Tomtom lead with a fused car plug to run 12v to Rider 450 Mount... I get 5.54 volts at the pins on the mount....

    I have a question. Does Motorcycle mount for Tomtom Rider 400/500 have a usb charging port or is is strictly hardwired to the bike battery? If it's the latter I will not buy one and just use a waterproof case with backup charging brick in a waterproof case, together with my RAM XGrip mount I already have.
    My unit is 2nd hand. I assume they did not sell the bike mount because that would have involved disconnecting from the bike battery). I did get car mount with it. I like that car mount has micro usb charging pot. If bike mount does not it is useless to me. I have no intention of wiring anything to my bike battery. So if someone can te me whether bike mount has a micro USB charging port I would much appreciate it.

    Bike mount is 12V. It has a build in 12V to 5V converter.
    Powering the bike mount with 5V doesn’t work.

    I have seen a post from someone that removed the 12V to 5V converter in the bike mount and powers it with 5V USB now.
    So when you are good with electronics.....

    Hi
    @evermom4aj
    Welcome to the site....
    You will need to find a 12 volt supply....
    Is there an accessory connection point somewhere on the wiring harness
    _________________________

    Or Modify the Mount as suggested in @RoadRider post above...
    Note... The above will void your Tomtom guarantee....
    All the usual disclaimers apply, all the above is at your own discretion

    __________________________

    Copy & Paste from one of my earlier posts... The user wanted to use the Rider 4/5xx on an old Brit bike with 6volt electrics....

    My Brother-in-law is an Amateur Radio User....
    We used his Bench DC Power Supply (Variable voltage) to test my Rider 550 Mount

    The Rider 550 Fully Charged 100%
    Connected the Rider Mount to the Variable Power Supply Set to....
    12.5 Volts... Readings across the Pins on the Mount = 5.55 Volts
    With the Rider in Sleep Mode... I Clicked it onto the Mount
    The Rider Started up OK

    Also Tested the Mount at...12v,11v,10v,9v,8v,7v....
    Readings each time across the Pins on the Mount = 5.55 Volts
    With the Rider in Sleep Mode... I Clicked it onto the Mount at...12v,11v,10v,9v,8v,7v the Rider Started up OK each time

    At 6.0 Volts... Readings across the Pins on the Mount... Was more or less Zero (slightly varying but hovering around Zero)
    With the Rider in Sleep Mode... I Clicked it onto the Mount the Rider Would Not Start Up
