HT Caps, electrical questions

[hmmmnz]

ok kids i have a couple of ht caps here 1 of which i was going to use,
bear in mind these are 2nd hand caps,
but i thought i'd test the coils i was unscrewing them from while i was at it,
1 tested out ok at 26kohm but the other coil tested out at 1.85Mohm
now thats quite a difference,
no worries i thought, they are just spare coils i had lying about,
any way unscrewed the ht caps and thought i'd just pop my meter either side of it,
and 1 cap i got a resistance of 10.9 kohm
and the 2nd had a resistance of 1.87Mohms

so any way i know the second cap is fuct,
but why does the first one even have a resistance??

Hi , could you explain how to use a multimeter to test coils mate ?

Caps have a resistor to supress TV / Radio Interference.

You'll have one of: resistive plugs, caps or ht leads for RFI suppression.

Use all three together to suppress RFI to the point where you get no spark at all. Use none for a great spark and messing up everybody's tv sets.

cool, i think i might just have to invest in non resistive ht caps awesome

Youll have fun finding non resistor caps these days.

Not to mention all uk spec plugs are resistor plugs.

I ran my previous GSXR1100 with J9A non resistor plugs, high output coils and silicone 1ohm resistor leads. The leads prevent too much noise without excessive losses.

Non resistor plugs are easy. Same code number, without the R.

So B8HS would be non resistor, BR8HS would be the same plug with a resistor.

Too much resistance kills your points too, eats away at the electrodes.

check the ht caps as well, and make sure all the resistances are the same, the cap is more likely to be the fault than the coils,

cool, the cb isn't really a high revving motor, and its recomended to have nonresisive plugs anyway
nice find though

A lot of bikes have to use resistor plugs to stop the RF interference scrambling the various black boxes. There is no real need for them on points ignition bikes.

Try riding a 350YPVS with the powervalve controller chattering the exhaust valve open and closed at random intervals though! "Hmm. Ok, we'll put the resistor plugs back in then shall we."

Or there's www.sparkplugs.co.uk

I've used them before, no problems. See if you can find a Nippon Denso equivalent to the NGK plugs you're supposed to use. NGK quality control seems to have gone down the toilet in the last few years.

They dont seem to do alot of non resistor plugs.
