With the ignition coil removed from the motorcycle and the ohmmeter set to the RX1K scale place the ohmmeter leads on the secondary coil windings B (middle terminal) to R (rear secondary terminal/socket), B to F (front secondary terminal/socket) and check for secondary coil winding resistance which normal resistance range will be 5. Single bolt hole for moun You state you've changed the coil so, we'll assume for now it's fine. The Check Engine Light will also be set off if the computer detects an issue with the ignition coil signal or circuit, such as when a coil burns out or shorts. Almost all automotive coils use a 0. To obtain a higher output the regulator connects the field to the D+ dynamo output. 81 ohm of resistance. In a motor, current is supplied to the coil which induces a magnetic field which is opposed by that from the magnet, causing the coil to move (rotate). The ignition coils supply a higher voltage for the secondary circuit, which is comprised of the secondary windings, the spark plugs, and the spark plug wires. b. After a lot of checking wiring, coil resistance and anything else I could think of and getting nowhere, I took the coil off and rigged it up on the bench directly to the spark plug and battery. It's common most of the way, though, so most of its run wouldn't affect just one coil. We will dismantle your dynamo, test the components and replace any faulty components. Either 12V across a 3-ohm primary coil or 6-9V across 1. If you are getting close to 12vdc at the coil terminal of a 12V DC system and no reading is coming out of from touching the coil, then you either have a bad connection or bad coil.
