If your moped uses a standard European style terminal strip, you can alternatively attach the test condenser directly to it at the ignition wire and ground connection without using the optional leads. . Step 1. If the test shows any other reading, then leaking is indicated, and the condenser must be replaced. This action places charge in the condenser. The easiest way to test whether or not a condenser is working is to add another one to the ignition circuit somewhere. These two tests more closely stress the capacitor in the same way actual operation does. The two months later another one failed after only 257 miles. But considering that a condenser is a cheap part, and you should always carry a known good spare anyway, the condenser tester seems a bit overboard for the average shade tree mechanic. The metal case of the condenser is the grounding point. Here are some common symptoms that hint towards having failing points and condenser: 1. A zero means the coil shorted internally. When testing the condenser with a multimeter, first isolate the condenser from the engine by disconnecting the lead wire. That is what causes the pitting, blue looking point contact ends and short lived points. What Is the Break Free From Plastic Pollution Act?

How to Test the Coil on a Ford 8N. The needle on the meter should move slightly toward the right before dropping back to the left. The meter's needle should jump slightly to the right (toward 0-ohms), then should drop back to the left towards infinite resistance). Testing can also verify a suspect condenser that might fail soon after installation. There are seals on the part that leak with normal wear and tear. Switch the volt ohmmeter to the ohms position. If the condenser goes bad and loses its ability to store the energy, the current jumps across the points in the open position which causes the ignition to fire erratically, resulting in backfiring. Remove the condenser from the engine. When a condenser goes bad, the engine will backfire and it will have a noticeable misfire while running or attempting to start. The ignition will likely work with any capacitance value between 0.05 and 0.6 microfarad. How can you tell if an auto ignition condenser is going bad? Set the resistance range to the highest setting.

Remove the assembly mounting bolts using a ratchet and socket. Vehicle not starting. In operation the condenser will "ring" at up to 300 volts, so the condenser needs to be rated much higher, no less than 600 volts DC. If the test shows any reading other than infinity, the condenser is leaking and needs to be replaced. The tester applies a high voltage to test for leakage and measures the storage capacity, or capacitance, of the part. (Yes, an ohm meter has a battery). If the reading doesn't get very high, maybe only 3Mohms, then cap is bad. I recently rebuilt a 69 Barracuda Wiper Motor. Remove the condenser from the engine. However, there also are digital meters with a capacitor test function and they will show actual capacitance in mfd's. But a digital without capacitor test function won't tell much about . Many people will replace a condenser with regular periodic maintenance, just because they have no way to tell how much longer it might last. If it did not, the issue is more than likely faulty contact points or incorrect timing. Set the resistance range to the highest available setting (if it is selectable).
