    Hi,

    By 1 of the USB ports shorting out, they,re probably all inter-connected. hence blown fuse on motherboard to USB Ports.

    Test with a multimeter. 5volts on 2 outer pins of USBs.

Motherboard dont have fuse has diodes which act similar to fuses but wont be blown.only things that will blow in that area are transistors or capacitors;but if these were blown usb's would not be detected.
in device manager were its says working correctly it relates to software istalled and working properly it cant tell u that the hub connection is damaged internally.
if your usb's are on card and connected to motherboard they can be replaced otherwise if built into motherboard youll have to take it to repair shop.
if the only problem is when u connect a usb device and not causing any other problems,u could use usb hubs that go into the pcmcia

Right turn signal quit working on my 2011 Harley heritage Flstc . I am having trouble finding the fuses. Looked under the seat, side panel. Where the heck is it.


Hi Jim, there is a black plastic box behind the battery lift the top up and away to access the fuses, before diagnosing any turn signal issue make sure the bulb is good and the light fuse has continuity. If no turn signals work the cause could be a faulty turn signal module or the connector going to it, look for corroded, loose, or broken pins/sockets. Contact spray cleaner is great for removing corrosion. If your speedometer does not function properly it will have to be fixed first because your turn signal module gets the data from the speedometer for normal turn signal function. If your front turn signals don't work use a test light to check for power and ground at the bulb socket, then start backtracking the wiring through every wire connector to the turn signal switch/button and check for continuity, go all the way back to the fuse if necessary to find the cause of the malfunction. If your rear turn signals don't work check your rear fender wiring harness connector first for corroded, broken, loose pins/sockets, power, and a good ground, (the harness connector is usually located under the seat on the front of the rear fender) then keep tracing the wiring look for obvious harness damage caused by the rear tire. If you still can't find the malfunction backtrack from the rear fender wiring harness connector. If one side does not work you could have a faulty turn signal switch or module check for continuity. For more information about your issue, please visit the websites below, and for specific information or questions, please feel free to contact me at xlch@mail.com. Good luck and have a nice day. http://fullmanuals.com/search/?q=2011+Harley+davison+heritage+softail

First put the required fuse dont go up you do more damage, For a fuse to blow you left rear side light and side light has shorted out to ground. left side rear light look at the wire are there any exposed, If no go to the side light inspect the wire are the exposed, if you see any repair it, Now if fuses keep blowing go the lamp belonging to that fuse and pull the bulb out with the bulb out an fuse installed twist the socket one at a time did the fuse blow,if it did you found the source,more than likely you ll need a bulb socket, as long as the wire are in good shape . Remeber correct fuses,No foil No nails No other Range just the required fuse

Any time I plug anything into any of the usb ports on my Advent roma 4001 my laptop switches itself off. Please help!


If the laptop switches off as soon as you insert the usb cable, there is a problem with either the usb socket or the cable. It is a safety system which stops usb power being re-directed down the usb data lines.
If you have tried multiple cables with the same result then the problem is with the usb socket. try a different socket (a usb hub will help if you are short of spare sockets).
Using a mall light, and maby a magnifying glass, inspect the usb port for bent pins or contacts, some sockets have pins (older dell machines especially) which are not supported at all by plastic backing strip and can be bent easily by inserting the usb plug incorrectly or by children armed with a pen etc.
If you find bent pins (there should be 4 pins evenly spaced or 4 metal strips along a plastic backing peice) remove the battery and attempt to realign the strips with a small screwdriver. switch the laptop on and try a usb plug in the socket - make sure you insert the plug gently and squarely (and the right way round). If the laptop still fails, have another go or ask someone else (who is nimble fingered and technically minded) to try it.
Don't give up (unless you find the socket is broken ie. missing pins) I can guarantee 99% that this is the problem.
good luck

The prop will turn on my minn kota endura 44 but it has no power is there a shear pin on this motor


Odds are you have sheared the pin (slides through the prop shaft) holding the prop, or you have damaged the slot on the prop that the pin sits in.

Prop is secured to the shaft with a metal nut, or flat plastic wing nut. Remove the nut to remove the prop. You may have to pry, slightly, the prop from the motor housing. Removed, you will see a whole in the shaft where a pin should be located. If the pin broke, it probably hit the floor when the prop was loosened. If the pin is intact, examine the rear side of the prop and look for damage to the plastic slot where the pin would sit making contact.

If you've snapped the pin, you can make a replacement with a nail using a hacksaw. Replacement pins can also be ordered from Minn Kota. If the back side of the prop is damaged (recess for the pin to sit), the prop is toast. Replacement props are often carried by Walmart, and include a new pin.

If neither part is broken, perhaps the prop was just not seated on the pin correctly allowing the prop to freewheel.
