My buddy, John L. (who owns an Arctic White '88), took ownership of a problem that will strike all owners of S4's, GT's ,and GTS. Here's a crosspost from John on RL:
All, I've been working through an interesting project in our [my company's] circuit/electronics lab. Thanks to `soontobered84`, I have a nicely fried fan control module from an S4->newer 928. Thankfully, the folks are also gear heads [Cobra kit, 308 Ferrari, etc]; so they graciously reverse engineered the entire circuit board for us. Typically, owners will replace the MOSFET's [aka, "fets"] in the unit. Rather that putting together a simple fix, we decided to reverse engineer the entire circuit in order to upgrade it to modern components. In order for us to calculate the appropriate costs, I would like to gauge the community interest in buying/transferring their S4 fan control switch to a brand new circuit design [fabbed on a modern process].
I _do not_ yet have any costs. Its highly dependent upon volume. It will likely be competitive with or less than current used/refurb models.
