coil

[bodger]

i ordered a coil RTC5628 .... and they sent me a 12v ballast coil ....
ive got a 35DLM8 Dizzy ..... is that going to be ok ?

Dunno if your coil will be OK but you can get an Intermotor one from the likes of Camberley Auto Factors which will work for about 15 quid. The one you want is for a Mini Metro, the part number is 11410

thankyou sidecar..
but the one i have was only £10 ... just want to know if they sent me right one ....
if not it will go back for a refund

The factory fit coil on my SD1 EFI with DLM dizzy is made by Bosch. No mention of it being a 9v coil.

Do you have a ballast resistor in your system - something similar to this:



If not, I think the coil description means it is intended for a 12 volt ballasted system.

What you ordered - RTC5628 - is correct for the original 35DLM8 distributor normally used in an unballasted circuit, but unless the actual coil is marked as such you should ask the vendor to clarify.

Technically, I think being described as '12 volt ballast coil' can be interpritted as the wrong item because it expects to see the full 12 volts during cranking and, due to the ballast resistor, 9 volts thereafter.

The wrong item would over-heat.

Thankyou Ramon ... theres nothing like that in my setup ...
mine is 12v feed straight from the ignition

12V BALLAST COIL ...going back ..

12V ELECTRONIC COIL ... on the way.

Thankyou everyone

A well designed electronic system has no need of a ballast resistor - the electronics should take care of varying battery voltage.

Should, of course, doesn't mean does.

[bodger]

well designed on the part of who ?

they are so simple .. 2 wires from the dizzy to the coil and a positive feed to the coil ....

thats it

That's all that's needed as the amp has a ground too so can sense the battery voltage. Or it could be internally regulated to run on the lowest voltage likely - say 9 volts - and a suitable coil provided.
