Intermittent problems are always the hardest to track down.  Multi wire cables with a random broken wire or connection have been my nemesis for years.

Coupling between power leads of any kind and sensor leads is always suspect, and this is a perfect example. The other cause would probably be traced to a difference in the components in the input circuit of the fuel flow meter. Small production variations that do not impair the apparent performance of one part of the system may still cause it to affect another part. 

Good detective work on finding the link that caused the problem, and good choice in changing the other units as well.

These cars were originally built in the 1970's by Rohr using Turbomeca gas turbines. Our company remanufactured them in the late 90's with updated engines and electronics. I don't believe Rohr is around any more, but Turbomeca still has engines in several GT rail applications around the world. They are an awesome little power plant for their size. They really shine for running an APU generator.

Absolutely!, Turbomeca produces excellent turbines, just look at the repowering of the Sikorski S-76 spirit helicoptes, which were marginal with their original engines by Allison, that surpassed all expectatives when they were re-equipped with Turbomeca Arriel 1S (and 1S1/2S2 versions in later models). Turbomeca engines are outstanding from both size/weight vs performance.  A happy engine makes a happier helicopter pilot!
