Possible coil problem

[edcphoto]

I accidentaly left my key on in my CA95 and now I can't get any spark or power to the lights. The battery has been recharged. Somewhere I read you can ruin a coil on these bikes if the key is left in the iginition and on.

I am so close to having this bike operable this is just killing me. Please advise as to best way to check a coil and if it is fried can I get an after market or do I need to find an original.

I've done that very thing - last year I left the ignition switch on after riding my 1972 CB175, overheating the coil and ruining it.

You should be able to quickly confirm that the coil is bad with a multimeter. Between the primary wires (low tension wires) it should have almost no resistance, maybe a few ohms. If the circuit is open (infinite resistance), the coil is likely bad.

You can use aftermarket generic coils, as long as the coil is designed for 6 volts and has dual leads. With aftermarket coils, the main challenge is usually finding a clean way to mount it, since they almost always differ in style and mount points. With the Benly, the inside of the stamped frame provides ample mounting options.

6 volt dual-lead generic coils are not as plentiful as 12 volt versions, but we should be able to find some alternative if you can't find a used CA95 or CA77 coil.

Here's a generic one for about $50:

It's odd to loose spark..and lights. Check your fuse just for kicks.

Good catch, I didn't see the comment about the lights, too.

I had checked the fuse and it seemed fine but I went and checked it again and now we seem to be OK. Perhaps it is just a contact issue so I'll clean everything up on the fuse case. Hopefully that is the end of this problem. On to getting the baby running and operational. Lots left to do but the end is in sight.

Will have some photos eventually.

Breaths a big sigh of releif.

The exact same thing happened to my on my CA160. There is (or was) a amall spring at the base of the tube contact that corrodes away making the contact loose. I went to the auto parts store an bought a replacement fuse assembly and spliced it in.
