Bruce,

Most problems as you describe are due to the connections on the battery or starter being loose, corroded or dirty. Clean your connectors ( the big wire ones) at your battery, starter relay, starter, and ground (just follow the big wires from your battery terminals) and I'm sure you will find one or more connections along the way that are corroded or loose. Make sure the connections are tight, clean and free from corrosion and your timberwolf will crank over just fine.

SOURCE: yamaha timberwolf 4x4 carberator issues

Hi,

Firstly, if you are not a mechanical person you should never buy a vehicle that does not run.
However, here are some basic tests.
1. Connect a good battery.
2. Remove the spark plug.
3. Turn the motor using the starter motor or kick starter.
4. check for spark by inserting a new plug into the plug cap. (make sure the plug is grounded).

If the motor turns freely and there is spark, chances are good that the motor will run. This does not mean that the motor is in a good condition. Only with the motor running will you be able to know for sure.

You will now have to source a carb and fit it to the 4 wheeler.
Fitting the carb is not too difficult. Check that the intake manifold is not perished or torn, and remember to use the airfilter.

Enjoy the ride !

I found solution. In my case problem was with connection next to the small electronic module next to the gear wheel. It is module directing red light in proper 'P', 'R', 'N' and 'D' letter.

SOURCE: battery is fully charged on my 205 and yet it turns itself off

Can it be turn on when the device is attached to the cradle with electric supply?
If so, I think the battey is aged and it cannot be charged to the operating voltage to turn the device on.
A change of battery is required.
I had such a case recently.

1999 Yamaha Timberwolf 250 will not turn over. Took it to someone they said it was stator. Replaced stator and spark plug still wont turn. There's no noise anywhere.


Hi, Anonymous and the usual suspects are:
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Discharged battery, needs to be 12.5 volts or better and be able to pass a load test if necessary.
4. Check the 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.
5. Tip over sensor needs a reset.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand or clutch pull in switch/sensor.
9. Starter control circuit, relay, or solenoid faulty.
10. Main fuse or circuit breaker may be blown or faulty.
11. Check for engine trouble codes.

1995 Timberwolf. When I try to start it, all I get is a click and it will not go into gear. What's wrong?


Hi, Brooke it should be noted that in order to "PROPERLY" diagnosis any electric starter issue it is "IMPERATIVE" that you begin with a fully charged battery 12.5 volts or better and be able to pass a proper load test, and the usual suspects are:
1. Battery terminals have loose or corroded connections.
2. Battery cables faulty due corroded or broken internal wiring at the cable connector especially the "NEGATIVE" cable which needs to be checked at "BOTH" ends.
3. Battery voltage, 12.5 volts or better,to the main circuit breaker to the ignition switch to the security/ignition fuse to the TSM/TSSM module to the engine stop/run switch to the starter button to the starter relay to the green wire that connects to the starter solenoid has dropped more than 1/2 volt.
4. With a voltmeter connected to the battery, the ignition switch in the on position, the kill switch in the run position, the starter button depressed, starter engagement should not bring voltage below 8-9 volts.
If a lower voltage is produced a proper battery load test should be performed with a load tester to validate battery integrity or battery replacement.
5. Faulty starter relay, check continuity.
6. Faulty starter solenoid, check contact plate and shoes for excessive electrical erosion/etching, refurbish as necessary or invert contact plate and use the virgin backside. Check contact shoes for being loose. Replace solenoid if the negative function is still a final outcome.
7. Faulty starter, bench test starter with a 12-volt battery if negative function check, decontaminate and undercut armature commutator segments as necessary, check segments with an ohm-meter probe each one and the segment next to it for shorts. Have the armature tested with a growler and field coils, and brush plate with an ohm-meter for opens, shorts or grounds. Replace brushes if less than .438" It is generally cheaper to overhaul/refurbish a starter motor than buy a new one.

'94 Timberwolf 250 2X4 starts great when I have battery charger hooked up, coughs, backfires and dies when I unhook the charger. NEW Battery, fully charged, seems to crank well when charger is OFF, but...


Hey Ccp.. A new battery and it did not help the cranking issue?? hhmm... PLEASE take the battery and have the CCA (Cold Cranking Amps) checked... just because its new and has voltage does not mean its a "good battery"... It takes AMPERAGE to crank and run your machine.. (*see 35 amp fast charge!!)..Autozone, O'reilly's, a battery shop can check the CCA... once you have MADE SURE the battery is good, then you can proceed to diagnosing the real issue...This is the procedure a professional mechanic takes..so do this first... once you have determined the battery is (good or you got a new one)..and ... once you have the machine running,,WITHOUT a charger hooked up.. time to check the output.. you should get 13.5+ volts at 3000+rpm.. if you are not getting 13.5+ volts, its time for electrical diagnosis...This manual should have all the electrical specifications needed to diagnose your issues...
