The original charger (Delta-Q model 910-7201) hasn't been manufactured new since 2005. It was custom built for Ford, and the charger had a custom interlock circuit to interface with the instrument cluster. As a result, the cluster and charger are NOT compatible with any other. Connecting any other charger may lead to permanent and unrepairable failure in the cluster. GEM chargers are NOT compatible. It is possible to defeat the interlock, but Electrons In Motion LLC will NOT provide that information, due to liability concerns.
Delta-Q has designed and built a new model of charger that is fully compatible with the Think Instrument Cluster interlock, and it has an integrated 400 Watt 13.5 Volt DC/DC Converter, and it's the ONLY charger that works properly. It's a current model, and is fully connectorized, which is a major improvement over the 910-7201 Ford model. There's quite a few major improvements in this charger. Contact us for the charger, install kit, mounting plate and instructions. This retrofit is what I'm replacing the a problem charger or problem DC/DC Converter.
