I bought a new part # STC1184 ignition amplifier from Amazon for my ’93 LWB, and just verified via RovahFarm.com that this is the correct #. They sell the same part #.I installed it and the truck wouldn’t even fire. Swapped back to my suspected bad amplifier, and the truck started and ran again. Swapped back to the new one, truck barely fired, stumbled over a bit and then died. Swapped back to the suspected bad one and it started up again normally.Just for kicks, I tested both at the 2-prong input with a ohm meter on the 200k scale, the suspected bad one tested something like 16.5 (what does that mean on the 200k scale?), the new one tested 75.5.Is it likely that the new one is faulty? That sounds like a dumb question because obviously it IS, the truck won’t run using it. But I have ZERO confidence in buying another, whether from Amazon or a Land Rover seller, if these things are that sketchy or delicate. I guess for the relatively low price I’ll have to go for it, but I’m also going to buy a GM amplifier and research splicing that in.For background: Truck runs fine for 6-8 miles, then develops the misfire characteristic of a bad amplifier. I can only assume it’s heating up within this time, causing it to fail.
