Which Coil Do I need?

[jdobson]

I need to get a replacement coil for my Rover V8. The current set-up is a coil sat on top of what I think is an amplifier pack. Unfortunately I cracked the top of the coil's plastic casing when trying to take a terminal off. The replacement I bought from REPCO does not seem to work so any suggestions on what I should ask for when going to the likes of REPCO / Super Cheap? The engine is a 1984 and it has Stromberg carbs (if that makes any difference).

Alternatively, should I just get a new coil and amplifier - I have heard that a Bosch set up may be better than the Lucas (surprise, surprise). Could I just get a new coil for a Discovery perhaps?

Thanks

Ditch the original amp amd fit a Bosch BIM024 amp with a new 12 volt coil. Bee Utey has done a full Tuitorial on this in a thread - will see if I can find it.

Edit - here it is - Lucas ignition amplifier replacement by Bosch 024 (https://www.aulro.com/afvb/technical-chatter/96950-lucas-ignition-amplifier-replacement-bosch-024-a-3.html) - easy and effective. I did this to my 86 RRC that had the same amp yours does.

Many vehicles in the 80's ran this module so you can get these second hand pretty easy but new ones are readily available - copies are plentiful so be careful - make sure it's a genuine Bosch unit - these go for a bit more - around $70 IIRC. The knock offs are half this.

Agreed.
Buy the amplifier and maybe coil from Bee utey, Save yourself a tonne of worries.
Take your time and Read the Instructions carefully...

Being such an old engine with a low compression ratio, - even when new- you don't need the most powerfullest coil on earth.

Take the opportunity to check / replace your rotor button, there is a 'wrong' (Ford?) part number which is fractionally longer (better?) than OEM which incidently, works ok.

Check integrity of the Distributor cap.
And the vacuum advance diaphragm, and operation. Oil that pad, -you know, that no-one ever does...
- Replacement diaphragms ARE available at reasonable $s from a place up in Queensland, IIRC.

Oh, you may as well chuck away a few more $s and replace the IGN leads.

$park Plugs OK ??? [bigwhistle][biggrin][bigwhistle]

(Or, 'Why should I be the only one who starts with one...then ends up replacing Everything.?' )

Be careful if you pull the rotor button off - there's a good chance you'll pop the advance springs off doing this on a dizzy that hasn't been touched in years - if the rotor button shaft isn't already rusted to the main dizzy shaft - again, Bee Utey has a thread on this and the repair to stop it reoccuring - basically a drilled and tapped hole - easy enough to do and again, something that I've had to do myself.

It used to be a Bosch 717 transformer coil but not with the stock amplifier.

If you use a BIM 024 , I think a 717 will work.

The 1984 system runs a Chev HEI module inside the tin box which should handle most electronic coils. But for a quick and easy replacement I'd try a Bosch BIC290 which should just fit in the stock position.

Just to let you know, I went with the Bosch upgrade and it worked perfectly. She is roaring once more!

Now to work out where the coolant leak is coming from.... it's in the alley of the V8, below the inlet manifold... guess it could be a leak from the thermostat housing or heater pipes?

[bee utey]

Take a ring spanner to the visible inlet manifold bolts, they may just be loose. Inlet gaskets on these things should be retensioned at least once after fitting. A new one occasionally isn't a bad idea either.
