Resistors R30 and R31 on pcb 4233-1288d-b completely burnt.

Resistors R30 and R31 on pcb 4233-1288d-b are burnt beyond recognition and need to be replaced. They conect directly to the voltage and resistance measurement terminal on my wavetek multimeter. I have searched everywhere for a wavetek dm27xt digital multimeter schematic in order to find out their sizes and types.

    I will try to find our wavetek multimeter in our office - I looked today but could not locate it. If I find it, I should be able to see the parts and tell you what they are. Bernard

    r30 is 100 ohms, R 31 is 47 ohms

  • Bernard Feb 09, 2012

    R11 looks like 500 or 5k, green black, black, black then white - is 1% value
    with meter to measure across it, I get 903 ohms, but that may vary with front switch setting, I did not check that-but I can send u photo - bmsbms.0123@gmail.com
    C01 is chip cap, not easy to know value - could be .1 uf or smaller

Intelliroute 520 wont connect to my pc


The answer to this question and many others can be found in the FAQ section on our support page at www.randmcnally.com/support. Additionally, for instructional videos on many of the TND & RVND features please visit the Rand McNally You Tube page at www.youtube.com/randmcnallyonline.

To troubleshoot a connectivity issue please try the following:

  1. Ensure the cable is secure on the device and computer. Disconnect and reconnect the device.
  2. If still not connecting and the cable is secure press the rest on the back of the device while connected to the computer.
  3. If a reset does not work then disconnect the device from the computer, wait at least 10 seconds and try another USB port on the computer.
  4. If another USB port does not resolve the issue disconnect the device, restart your computer, then connect the device.
  5. If all the above fails you can Reinstall the Device Driver. Navigate to the Device Manager on your computer. Please note this will vary based on the operating system you are using. Once at the Device Manager screen locate Universal Serial Bus Controllers. Click the arrow/triangle to the left of the Universal Serial Bus Controllers to expand the drop down list. If the device driver is the issue one of the items listed will say Unknown Device. Right click on Unknown Device and select uninstall. Once the uninstall has been completed, restart your computer with the device still connected.

If the device is not recognized after trying all these steps you will need to contact Technical Support for additional troubleshooting. To properly diagnose and correct a connectivity issue you will need to have the Rand McNally Dock Installed, a broadband internet connection and your device available to connect when instructed to do so. If these items are not available, we may not be able to resolve your issue.

My GTM 20 tip got unscrewed and the parts fell out. I put the parts together and then found out that both the car socket fuse and the GTM 20 fuse were busted. I replaced both fuses. The car socket works...


The GTM 20 can be repaired. It's likely that either you're not using the correct fuse or there's a short circuit. The short circuit would be caused by the metal tip, spring or fuse touching the outer part of the plug. There's a repair kit available from http://www.gpscity.com/garmin-replacement-parts-for-gtm2x.html

The charger/traffic receiver glows green but it does not charge the unit. How can i test whether the fault is a, the charger, b the cradle or c, the unit


hi,

1st of all let me say im on my 3 cradle now for my 760 because the connection inside the cradle where it mounts to the board is pretty poor.

since you said the traffic/charger has the green light lite, that means the charging part of it is working.

you can verify if its the cradle or the connection on the bottom of the gps where the cradle mounts by using the usb cable supplied with your garmin.

plug it in for a while, then check the battery meter after you unplug it..if its charging, the meter would have risen beyond what it was before you tried to charge it. the same can be done with a regular garmin charger (the one that uses the usb connection for the car charger to charge it)

I have a Garmin Nuvi 770 that won't "speak" when navigating


Frequently (about 20% of the time) when I have my Nuvi 770 plugged in, in the car and I turn it on, it gets stuck at the start up screen where it says, “Loading maps” I wait several minutes and it never completes. Then I turn it off and turn it back on and it comes right up, but with no voice. When I go to Tools > Setup > Language it shows no language and I cannot select one. I have to plug my Nuvi 770 into the computer, run web updater, it detects that I already have the software loaded and I select the option to download it again. When it has completed, I unplug the Nuvi and then go to Tools > Setup > Language and select American English.
