Bougicord 403 Class B

Post by **ebdl** » 06 Jan 2006 07:06 pm

More trouble finding spares... I'd like a set of HT leads that are actually designed for, and fit, my car. I've tried two sets, one from Lucas and one from another manufacturer I've never heard of before. The problem I have is that the centre lead that goes to the coil doesn't fit. It is fairly obvious which end is supposed to attach to the distributor cap, but the other end is simply not long enough to fit into the Ducellier coil.

The cables I have are Bougicord 403 Class B. They are red and so old that they are almost solid. I wouldn't be surprised if they're 22 years old. Volvo can supply me with the four leads that go to the spark plugs, but for a reason known only to themselves, do not supply the lead that goes to the coil. The very one that won't fit from aftermarket sets.

HELP!

take the lead into halfords and go thru the boxes till you find one which matches?

Here is the part number for the

Bosch - RBUS 18

correct leads and I know they fit

Thanks very much - looks like a trip to Halfords for me

It has really anouyed me in the past getting supplied with the wrong leads, that is way I brought in a few at the same time by part no once I found the correct ones.

is the different specification for the leads merely the length or do different ignition systems need different resistance leads etc.....

The problem I'm having is that the lead to the coil simply isn't designed to fit the hole it has to go into. All of the leads to go to the coil have some kind of plastic clip at one end and a very short 90 degree connection. In my coil the lead needs to be pushed in quite a long way and so I need a long, straight end to the lead rather than a short, bent one.

From what I've read, leads have different class ratings, related to the kind of temperatures they will work at. For example, the leads in my car are Class B, which I think is quite a low temperature rating. Most modern leads seem to be Class F.

I think the differences between most sets of leads is simply the lengths of the leads and the kind of connectors they have on the end

there are significant differences between lead types, because of the resistance!

most of the time these silicone leads will have a carbon/fiber core, with a high resistance.

With a breaker points distributor, you would be better off with copper core leads, these have far less resistance and will give a marginally better spark.

The same goes for plugs, if you have a choice between resistor and non-resistor types; take the non-resistor!!

given the position of the coil (front of the car) and distributor, it is not very likely to get an interference problem with the audio equipment.

the rotor is always a resitor type, because the law requires it to be.
(would give severe interference if not!)
