An Electrical Modification On My Ford Bronco II…

The motorhome is parked at Thousand Trails Thunderbird RV Resort along the bank of the Skykomish River in Monroe, Washington. I’ve been here a number of times over the past years and always enjoy it here. My scheduled departure date is July 8th.

Mary is at home tending to personal matters…home maintenance, family, friends, rentals, etc..  She has made her flight reservations to meet me July 29th in Bellingham, Washington.

In the early 1980’s, the first automobile computers started to appear. On 22,000,000 Ford vehicles between 1983 and 1995, it was known as a TFI (thin-film Ignition) Module. Ford initially mounted them on the backside of the distributor where they got very hot and resulted in the engine to stop running without any notice. After the engine cooled down, the engine would once again run…until the next time. It made one very hesitant to go anywhere for fear of when it would happen once again. A class action lawsuit resulted which you can read about by clicking this link…

Ford ultimately relocated the unit to another location in the engine compartment to satisfy the issue. I had had the problem with my previous 1984  Ford Bronco II and knew instantly what was going on when it happen to me for the first time on my current 1986 Ford Bronco II a few days ago. After about 30 minutes of cooling I was able to restart the Bronco.

I’m lucky it happened here in Monroe because I could call my friend and cracker-jack mechanic Kenny Coleman. He came over yesterday and changed the location of the TFI Module on my Bronco. The new unit with tax ran me $96. The entire project took two hours and Kenny assured me I should have no further problems with an overheated TFI Module.

The TFI Module behind the distributor is very difficult to access…


Here’s the culprit. Kenny told me the brown area on the left is where it got really hot causing the internal electronic failure…


Now mounted on a piece of aluminum angle to act as a heat sink, the unit is mounted atop the air conditioning housing. Kenny said the combination of the aluminum heat sink and unrestricted air flow for cooling will resolve any future problems…


Having a vehicle that could unexpectedly stall at any given moment is not a good thing. It’s nice to nice that potential problem has been removed on my Bronco.


Yesterday was a cloudy/sunny day at 72 degrees. Forecast for today is cloudy/sunny and 79 degrees.

Enjoying nice weather is another joy in the life of a full-time RVer!

Enjoying 65-75 degree temperatures with low humidity most of the year is a primary joy in the RVing lifestyle!

On October 27, 2012, I created a two-minute video titled America The Beautiful. The music America The Beautiful is by Christopher W. French. The photos, which I randomly selected, are from the states of Arizona, California, Colorado, Florida, Georgia, Louisiana, Massachusetts, Mississippi, Montana, New Mexico, North Carolina, Oklahoma, Oregon, Pennsylvania, Texas, Tennessee, Washington and West Virginia (not shown in that order)…are mine. Yup, That’s me standing in front of the Post Office in Luckenbach, Texas…Y’all!

      The blog you saw did not fix my problem. The problem was finally resolved ( I cannot believe I didn’t write a blog about it ), by purchasing a heat sink. Here’s the link…
      and installing it in the grill-work of my Bronco. Been almost a year…and no more problems. Buy the heat sink and follow the instructions.

        thanks a lot. i ordered the relocation kit from mccully. so if i am understanding it correctly the problem was the location of the tfi but i will just have to move it behind the grilling instead.

        would you mind sending me a photo (when you get a chance) of where you chose to put yours.
