LOW OHM READING - MEANS BAD INJECTOR COIL ECM FIRES FOUR AT A TIME ON 89'S IN LINE 14 -16 OHMS IS NORMAL LOWER OHMS RAISES AMPS BEYOND ECM CAPACITY AND ALL FOUR CAN MISFIRE
Depending on the accuracy of your Ohm meter, yes... it could very well be shorted.
6000-8000 ohms
Looking for coil ohms and stator ohms. And possibly the voltage comming out of the stator .
Is that zero ohms measured in circuit or out of circuit? To get an accurate reading it needs to be out of circuit. Next, which scale did you use on the meter? If you're measuring on the 5k ohm scale, you won't get much useful information about your pickup coil or high voltage coil. On the other hand, if you're getting zero ohms and you're on the right scale, the coil is probably shorted internally.
The coil on the relay should read about 70 ohms
In a Honda TRX90 Service Manual.
5 ohms
Distributor pickup coil resistance 140-180 ohms.
.93k ohms
In order to test a moped coil you need to use an ohmmeter. First you test the primary coil by touching the leads (2 wires with points on the ends that come off the ohmmeter) to the positive and negative terminals on the coil. The spot for the spark plug wire is not a terminal used for testing the primary coil. If your coil only has one terminal, other than the one for the spark plug, then the mounting hole is the other terminal. When you put the ohmmeter across these two points your reading should be less than 3 ohms. If the primary windings in the coil are fried, this reading is normally really high. The most common problem is the secondary windings. After testing the primary, you then need to test the secondary windings. To do this you touch one lead off your ohmmeter to the spark plug terminal and the other to one of the primary terminals. Your reading should be right around 10,000 ohms. It will most likely read 10K. It does not matter which primary terminal you use. It also does not matter which lead you use where. (When testing ohms the red and black leads are identical and the colors are not a factor.)
15 to 40 ohms.
