Common questions

Where is the secondary winding resistance on a CDI box?

Where is the secondary winding resistance on a CDI box?

Touch one of the outer contact leads and central, inner contact of the ignition coil. This is where the main wire connects to the distributor. Record the reading. This is termed as the secondary winding resistance of the ignition coil.

Where does the CDI box amplify the signal?

The box amplifies the small signal generated from the spinning magnet located in front of the pickup coil in the stator, just before top dead center (TDC), when your fuel-air mixture is ignited. The box can’t generate continuous sparks.

What to do if your ignition unit fails?

At home, I put the bike up on the jack and removed the seat, tank and side covers. I checked over everything again and could find nothing obviously wrong. I got our my Haynes manual and read through the troubleshooting steps. At the end I read about the ignition control unit possibly failing.

How can I tell if my CDI box is damaged?

The automotive should be switched off and allowed to cool. Use an ohmmeter to measure the electrical resistance of the CDI box in a quantifiable way. Different vehicles have specified electrical resistance within the coil. If the coil’s correct resistance levels fail to meet these specifications, you’ll know that your coil is damaged.

Is the ignition coil the same as the ground wire?

In other words, turning off the key is the same as touching the end of the ground wire from the ignition module to the mower frame. You have answered the question in a way that doesn’t make sense to me.

What kind of wire is the IGN SW coil?

Another wire is a Red power wire, that is split between the black plug, and the clear plastic plug. The clear plastic has the IGN SW Coil pink wire running to it. As you said, this wire is for the coil, that makes complete sense.

Where does the power come from on an ignition coil?

Yep, there is another wire that goes from the fuse block to the (+) side of the coil. This is how the coil gets power. The entire fuse block has a thick red wire leading out of it. This is definitely not a 10 Ga, but a lot thicker.

Can a faulty igniter wire render a grill useless?

A faulty wire in your ignitor system can render your grill useless. Luckily they are easy to replace, and the BBQ Depot as a varied selection of wires for all types of grill makes and models. To find your match faster use our brand filter.
