The field sense circuit does not draw any significant amperage (if any).

So if you're running loads through this smaller circuit, I suspect you're overloading its capabilities and shorting or breaking the circuit.

You are speaking to about the longacre one right?

Interesting, that is what we figured, but on many other cars we never had a problem, (4 others running for 3 years). But after those two incidences we switched everything over to just avoid using them.

And we never found any info on line to suggest what they were to be used for.
