Motorcycle Repair Questions? Ask a Mechanic ASAP
Do you have a volt meter?
A battery may indicate a full charge condition in the battery voltage test and the specific gravity test, but still may not have the storage capacity necessary to properly function in the electrical system. For this reason, a battery capacity or load test should be conducted whenever poor battery performance is encountered. To perform this test, Verify the battery is fully charged. Then hook a multi tester to the battery The reading should be 12.6 volts or greater. Engage the starter and observe the battery voltage while cranking the engine. Continue the test for 15 seconds. During cranking the observed voltage should not drop below 9.5 volts. If the beginning voltage is 12.6 volts or higher and the cranking voltage drops below 9.5 volts during the test, replace the battery.
Verify the battery is fully charged. With the engine running, connect the multimeter to the
Positive and negative battery terminals.
Test for Voltage dc with the multimeter. The meter display should read approximately 13.5 - 14.4 Vdc at idle if you need to raise the idle to see if the voltage reading raises with more RPM. If the voltage is lower than 13.5- 14.4 Vdc, The charging system is not charging the battery.
let me know your results.
common problems for the sportsman 700 are
if the battery and charging system test ok we can look other test to find the problem.
Does the "Check Engine" come on the meter?
the fuel filter is in the tank and not serviceable. I wold not replace part with out confirming what is bad.
Ignition coils on Power sports units rarely go bad. I have never replace a failed fuel injector. I have replaced ECMs on the rangers but it is because it will not spark one of the ignition coils. Usually It is no an intermittently thing when a ECM goes bad is just quits working.
Check the throttle body to see how dirty it is. if it is dirty clean it with throttle body cleaner or carb clean.
the thumb throttle free play should be only 1/8 inch of free play as it has a cut out system in the throttle and will come on if the throttle is not adjusted properly.
Yes you are correct. I was thinking the Ranger sorry about that.
To enable the blink codes, turn the ignition from "OFF" to "ON" 3 times, leaving it 'on' the 3rd time, within 5 seconds.Any "blink codes" stored in the ECU will display, one at a
time, in numerical order. The word END will display after all codes have been transmitted. Let me know what codes you have.
41 Air Temp Sensor: Open or Short Circuit to Sensor Voltage (ECU) OR Short Circuit to Ground
51 Injector 1: Open Load, Short Circuit to Ground OR Short Circuit to Battery
52 Injector 2: Open Load, Short Circuit to Ground OR Short Circuit to Battery
Check Battery Voltage (12.5VDC minimum)
90 % of the time on Polaris's it is wiring issue check at the ends of the connectors and where they go into the main wire harness on each of the bad components for chafing and broken wires.
let me know what you find.
