'74 CB360 Dual coil question
- Thread starter billyp
- Start date
They don't work. I've tried it. XT coils use the wrong current because it's a CDI bike.

I did wonder if that was the case, and the xt500 is points based.
But the coils seem to be single LT connection, so i’m unsure how to wire those?

At that price, you won't lose much if you try them. Those look very like the coils that many sites around the world are selling for around 30 bucks a pop. I have no idea how to measure impedance, but if resistance values are say 5ohm primary and say 8-15k secondary, i'd go ahead and use them.
The CDI coils I am familiar with have a single low tension lead to the CDI and I think that all points/electronic ignition coils are 2 wire. I haven't seen any CDI twin LT coils but they are probably out there. Motoplat and PVL are exceptions in that the coil includes the CDI circuit so they have two leads - one is charge and the other is timing pulse.
The difference is in what type of current they run off of. Some run off DC and some off AC. They aren't interchangeable. A bike with a magneto, like most dirt bikes of the era, use AC coils. The XT coils are AC. Our street Hondas use DC coils that run off rectified DC power.teazer said:
Do we know for sure that the coils shown are actually AC type coils? Just because the seller lists an application doesn't always mean he's right.
I don't have a 94 XT600 so I looked on line at wiring diagrams and it looks like it runs a 12v DC ignition system. Anyone know for sure?

You may have missed the post, but I have bought those same coils and discovered they are AC and don't work. That's how I learned all this- through my own fuckups. I have several coils I bought for my last 360 that don't work, and ended up rebuilding the stock coils. I imagine it's completely possible that the manufacturer uses the same molds and makes AC and DC coils that are identical, but the coils I bought that look identical to those coils that were for an XT do not work.teazer said:
That is entirely possible that they use the same molding. The set of coils I bought from Europe look identical to those and they run fine with a DC system. Maybe Sonrier can shed some light on this conundrum.

New points and condensers arrived in the post yesterday, so this afternoon i built up a new points ‘loom’ and rebuilt. For the loom i used ‘high temp’ 200c rated wiring, double insulated and new crimped and soldered bullet connections.
The new points dont bloody fit !!!
They bolt up to the plate ok but the ‘cams’ are too large and there isnt enough adjustment to get the required points gaps. The points were advertised with pics of japanese made items with black moving parts, but cheapo no marking parts arrived with brown parts and these didnt fit. So watch out for those.
I built the bike back up with the old points and had a test, with new lt and ht wiring and condensers, ran well in the garage but not been out yet.
I’m still awaiting two new NGK Spark plug connectors to finish the job.

WOW !
New NGK plug caps arrived so i installed those, checked the timing again, and pressed the starter.
Bike fired up immediately, never did that before !
So, somewhere in the replacement of the old HT and LT wiring, new condensers, new plug caps an old weakness was erradicated.
Took the bike for a good test run today and it performed fantastically, pulls strongly and revs really freely.
Stopped for a coffee and a chat, on the way home it’s not running so well, then dies at a junction, wont restart..... until i turn the fuel tap to reserve and all is well again.
Was having so much fun i ran out of fuel !
Need to find a next job to do, maybe swing arm bushes as havent touched those.
