Thread: Ignition Amplifier Module 3.9 V8 (Remote Type)

Ritters (OEM) - $400
Ritters (Unspec Aftermarket) - $200
An Aust Online Supplier (Unspec Aftermarket) - $170
Bursons (Aust made Tridon Model# TIM044) - $100

Anyone had any experience with the Tridon unit good or bad?

I believe the later dissy-mounted amp is the same as the remote one, both 3 pin ones. It fits the early dissy as well but needs an adaptor cable to a 2 pin plug.

Can't say I'd ever buy any of the above, a Bosch BIM024 amp and matching coil can be adapted quite easily and cost less that all of the above.

Thanks bee utey. A couple of questions.

1. Can the OEM coil be matched up with the Bosch BIM024 amp?

2. The OEM/ Tridon amp comprises 2 plugs and 5 wires. One plug (the underside bottom right of 1st photo below) comprises 3 wire from the dizzy (2 pin plug to amp and wire to ground) and the second (shown at right top corner of 1st photo below) a 3 pin plug (however only 2 pins active) going to the coil. In other words the amp comprises 4 pins plus an earth.

Which of the 4 pins on the Bosch BIM024 (2nd photo) match up with the OEM amp plug pins (noting OEM plugs have to replaced with suitable connectors to match the Bosch)?

Unfortunately I have needed to research V8 ignition a bit recently... bloody petrol engines

But at least the wiring loom doesn't leak oil.

I haven't used an OEM coil with the Bosch amp, because the OEM coil frequently fails itself. So I haven't tried.

There are many different australian production cars using the Bosch 024 modules so I usually get a second hand coil for $5. Suitable coils include Magna (carby) Holden/Ford 80-85 carby, Camira carby and any other car running Bosch HEI dissy. They rarely give me trouble, so long as they don't leak oil, easy to get a spare.

Pin wise the socket in the (Lucas amp) underside corresponds to 3 and 7 on the 024, plus an earthed shield. They connect to the dissy magnetic pickup. The vertical socket has +ve and -ve coil for the coil connections. Bosch is +ve on 15, -ve on 16. The 024 is earthed via its screws to the heatsink. All connectors can be 6.3mm flat crimps, although terminal 3 has a 4.8mm blade.

My post on the conversion gives a "how to" for connections, based on continued experience in keeping Land Rovers going for less cost than anyone else!

I should have said non-EFI diesels

bee utey love your work....

....but sorry I still have questions about your replacement ignition amplifier advice for 3.9 LR's with remote amp modules……..but in saying that please forgive me because you probably have forgotten more about ignitions systems than I will ever know. Unfortunately to compound things I also have an overarching EFI ignition system ECU compatibility fetish.

It seems to me the Bosch BIM024 amp you are suggesting as the bees knees for all D1 3.5 and 3.9’s EFI's (and to the extent one must also change the coil to suit) is a Bosch amp that was first fitted to carby vehicles and produced up to 15 years before the changeover D1 appeared. Senor Lucas had some probs but surely he was not this retarded??????

I note your point about cost savings but the difference in price between a Bosch BIM024 amp and a “plug and play”Tridon Model# TIM044 amp is a pidly $25 at Bursons/SuperCrap etc. Installing the Bosch BIM024 then requires butchering both dizzy and coil looms using new home made connectors (when we all know the heart of an ignition system is connection integrity) then add the coil change you are suggesting ...even if it from a $5 wrecker it will be an improvement??


However bee utey is your advice a case of not the LR amp being a dud but the LR EFI coil being so much a dud (by the way I can't find a car that has same Bosch coil as a 3.9 LR) to the extent you need to change the coil and that then brings the need for a different and compatible amp and the only one left standing is Bosch BIM024 ancient as it is???

If that is your advice I was unaware 3.9 D1 LR coils were so bad?

PS To add to the puzzle a OEM coil is about $80 new. I assume this is the old oil filled style. However a Bosch Coil (#0221122392) is $240 which I assume is the newer transformer type.
