Bosch Ignition Coil Resistance Values

Better is to test the coil under actual load. Bosch transformer ignition coil robert bosch has been supplying transformer coils as original equipment to the australian vehicle manufacturers since 1987 and virtually every locally manufactured vehicle had this style of coil fitted as standard original equipment until recently.

How To Test Ignition Coils With Basic Hand Tools Hd Youtube

Bosch coils are made in a number of countries with varying amounts of primary and secondary resistance.

Bosch ignition coil resistance values. Based from our experiment the coils have correct specifications and yield a healthy resistance and voltage. An ohm meter can also be used to test coil winding resistance. Just make sure to buy the one that matches your cars make model.

Bosch ignition coil provides ignition voltagethe function of the ignition coil is the amplification of the magnetic field in the secondary windings. Ignition coils all bosch ignition coils are built to achieve or exceed oe specifications and are known industry wide for their reliability and performance. Generally bosch ignition coils receive acceptable reviews online.

Run engine to operating temperature oil temperature about 80 to 90 c176 to 194 f. Secondary resistance values vary widely so consult a specifications chart for the engine you are servicing. The bosch coils above should have a primary winding with 30 to 33 ω resistance.

Tachometer can be connected to ignition coil terminals 1 and 15 of transistorized ignition coil systems. Hi tension terminal is about 10000 ohms. Bosch 221 122 001 coil resistance.

1 iron core 2 insulating compound 3 sealant 4 secondary winding 5 primary winding 6 cladding sheet 7 fastening clip 8 housing. Bosch ignition coils convert low voltage into high ignition system voltage creating an electric spark sent to the spark plugs which ignites the fuel. Its best to check the coils primary resistance with an ohmmeter a digital multi meter in the 200 ω mode.

For 12v coils the primary resistance between the push on terminals. Should be roughly 3 5 ohms. As a result of this development for original.

Primary side resistance from coil minus to coil plus is typically between 03 and 10 ohm on electronic ignition type coils. Newbiie how to test resistance on a bosch ignition coil. The high voltage on the secondary coil can be up to 40 kv depending on the ignition coil.

Unlike capacitor discharge ignition systems testing equipment eg. These coils have a modern design that makes them more durable. The secondary resistance from one push on terminal to the.

The opening induction voltage of the primary winding is between 300 and 400 v.
