2011 KTM 990 Adventure low beam blows and speedometer goes out


Hi, Anonymous if your headlight is not working, only one beam works, keeps burning out, blinking, or is dim the first thing you need to check is the headlight bulb for damaged filaments then check your light circuit fuse, then check your head light bulb socket ground wire for a clean tight connection, that being said the usual suspects are:
1. Faulty ground or power supply wire to headlight bulb socket.
2. Worn down solder contacts or loose fit of the bulb base in the socket due to vibration.
3. Worn, chaffed, or broken wires in the light circuit.
4. Corroded, broken, or loose pins/sockets in wire connectors.
5. Faulty hi/lo beam switch.
6. Faulty ignition switch.
7. Fuse is good but no continuity on both sides.
8. Faulty headlight relay.
9. Faulty wiring between battery positive and headlight bulb socket.
10. Weak charging alternator/generator.
11. Faulty voltage regulator/rectifier ground or overcharging.

The check engine light came on my KTM duke 125 after I was driving it in the rain what should I do?


Hi, Peleg it should be noted that the reasons your check engine light constant or flashing, will or will not start, turns over or not conditions varies from the year, make, and model and you should always refer to your owners/service manual for proper diagnostic procedures. It should also be noted that any type of prior work or event IE: adding accessories, electrical curiosity/adventures, laying bike down/crashes, rainstorms/bike washings just before EFI light issues started can be significant hints/aids into tracking down the gremlin, also carry the appropriate jumper wire to access fault codes to reduce the risk of being stranded or towed, that being said the usual suspects are:
1. Faulty Fuel Pump, fuse or system relay switch.
2. Battery starting to fail due to old age/damage, perform a load test.
3. Discharged battery, check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Faulty switches/sensors: run/off, ignition, clutch lever, neutral, side stand, tip over, fuel, and or their connections.
5. Broken wire or worn insulation exposing wire to a ground situation especially inside wire harness at tight bends around fairing brackets, under dash panels, under fuel tanks over cylinder heads etc. Many harnesses are open on the ends that will allow water to enter and accumulate at v-bends.
6. Check for generated fault codes.
Dielectric grease and contact cleaner are your best friends for wire/cable/harness connectors, look for corroded, broken, or loose pins/sockets.

Hi there! I want to remove my alarm system from my bike. It is a MetaSystems Defcom3 alarm. Although I managed to disconnect all connections of the alarm from the bike, when I try to ignite, the bike...


Are you connecting like color codes to like? Wires that were cut in order to install the alarm need to go back together as they were originally. It sounds like you're doing the right thing but you might want to double check the color codes to make sure you din't mistake one for another.

I have a set of hand controls for a 95-06 Harley with no diagram how Do I figure out witch wire from the switches go were


If you're simply replacing the controls with other controls, the color coding of the wires should be the same. Simply unplug the old wire from the plug and insert the same color wire from the new set. Now, if you're trying to install a later set of switches on an earlier model bike, you need a wiring diagram of BOTH the new switches and the old bike so you can figure out the color codes on the wires.

Good Luck

Starts and idles OK until I put it in gear, then it quits running like the ignition is turned off. Checked kill switch, neutral switch, kick stand switch, and clutch switch, all check out OK. Clutch pack...


I suspect a broken or loose wire in the headlight bucket or where the harness goes around the frame neck. Check your battery connections, fuse connections, and ground wires. After you you have loosened and tightened all the bolts, plugged and unplugged all the wire connections(make sure wire colors match up), Starting the bike and turning the handlebars back and forth. If all this checks out you probably have a dirty switch. You said you checked all the switches but maybe the failure is load related. Out of desperation I take the 35 year old switches apart on my Goldwing, clean them , and put them back together.It is possible you have a dirty contact in your ignition switch (dirt across the connections) that could be the problem. It sure sounds like a main switch problem, but, the only switch you are activating, when you put it in gear ,is the neutral switch and the clutch safety switch. Recheck those systems or replace them first. Try bypassing the swiches one at a time to determine which one is the problem. Be happy your not on a mountain top 600 miles from home cleaning an ignition switch with a pocket knife.

I hav a 95 berrta and im tying to put a head unit


Hello chrisuftring,

Here's a link to the wiring color code for the '95 Chevy Beretta.

You'll need to match the function of each wire from your head unit and the color code for that would be in your manual. Most aftermarket units are somewhat standard as far as power, accessory, ground, and speaker connections are concerned. But the wiring colors may be different for such leads as remote, power antenna, illumination, dimmer, and muting.

An Alpine head unit has the following wiring colors:
Blue - Power Antenna
Blue/White - Remote
Pink/Black - Audio Interrupt (muting)
Orange - Illumination
Red- Switched 12V+
Yellow - Constant 12V+
Black - Ground
Gray - RF Speaker (+)
Gray/Black - RF Speaker (-)
White - LF Speaker (+)
White/Black LF Speaker (-)
Violet - RR Speaker (+)
Violet/Black RR Speaker (-)
Green - LR Speaker (+)
Green/Black - LR Speaker (-)

With this head unit, you would wire Yellow to Orange, Red to Yellow, Black to Black, Orange to Gray, Blue to Pink, Gray to Light Green, Gray/Black to Dark Green, White to Tan, White/Black to Gray, Violet to Dark Blue, Violet/Black to Light Blue, Green to Brown, and Green/Black to Yellow.

Note that there are 2 "yellow" wires in your vehicle color code. You'll have to test them to determine which one is the accessory wire and which one goes to the left rear speaker. Using a 12V "test light" is the simplest. Connect one side of the light to ground. With the ignition ON probe the yellow wires. One of them should light the tester, the other one won't. Verify that the light goes out when the ignition is OFF and your have separated the redundant "yellows". The one that lit the tester is your 12V+ switched wire and the other one goes to the left rear speaker.

Hope this helps.
