If you’ve been following along with my plan to eliminate my Lucas ignition system you know we’ve had some struggles. Remember the goal, to replace the expensive and moderately reliable Lucas parts with easy to source, available in nearly any auto parts store, inexpensive (sometimes with a lifetime warranty) ignition parts.
No one wants to pay 200$(US)+ for an ignition module that takes 5 days to arrive from one of the coasts or 100$(US)+ for an ignition coil when you damn well know that a similar coil and ignition module for a 1977 Chevy Nova costs 75$(US) and both have a lifetime warranty. Before I owned this Land Rover I had never experienced an ignition module or coil failure….NEVER, on a dozen cars across the entire spectrum of vehicles I have driven.
Our current issue, while we have managed to source an ignition module for 25$(US) and a coil for just under 50$(US) the ignition modules are failing at a rate a great deal worse than the Lucas setup. Think, every 2 weeks I’m replacing an ignition module. I carry TWO spares just in case.
This is in all actuality worse than the Lucas setup. A great deal of science has gone into the conditioning of the voltage and current going into the module and coil. A lot of thought by people a great deal smarter than me has gone into figuring out what is causing the failure of the GM modules we are using to replace Lucas. We’ve come down to this, we need a coil that has higher resistance than the coil we originally sourced. So to that end we now have an ignition module AND coil from a 1977 Chevy Nova with the L6 engine. Matter of fact this is the coil used on 965 different models of cars look at the list here. There’s even 32 models of Jeep on that list! Even with all the models using this coil, this is not a coil commonly stocked at your neighborhood O’Reilly’s. That is a bit disappointing but it is to be expected. The ignition module which is the more common of failure points, is a very common GM part and available in most auto parts stores.
So if you are trying to do the same to your beloved Land Rover.
The coil is a BWD – Ignition Coil Part # E41 available for 23.99$(US) Lifetime Warranty
The ignition module is a BWD – Ignition Control Module Part # CBE4P available for 29.99$(US) Lifetime Warranty
I’ll be installing these this weekend and will keep you apprised of any additional failures and what we are doing to eliminate them. During a fit of frustration recently I purchased a new Lucas ignition module and official coil and I am prepared to put them back in and scrub this experiment. I was able to find them on Amazon.com below the cost of some Land Rover parts sites you have seen online and with my Prime membership they came to the house in TWO DAYS! That will work. It won’t work if I’m stuck in the middle of the Comanche National Grasslands 30 miles or more from the nearest parts store, so I guess I’ll be carrying a spare from here on out, perhaps even two spares.
I’m hoping to have a reliable rig for an Oklahoma Overland Group run to the western part of the state at the end of this month. If you think you’d like to go check out the Oklahoma Overland Group on the Facebook.
Thanks for reading and Happy Rovering.
