FAQ's

Before calling for tech support, many issues can be quickly resolved by reading the FAQs.

 

TST provides free tech support, but we need the SN and date of purchase.  So, when calling for tech support you will need to provide the PowerMax module SN (on a silver tag on the side of the module) and the date of purchase.  This information is needed for us to look up the PowerMax program and the type of harnesses that you have.  Also, if you are getting a Check Engine Light and/or any fault codes you need to include the exact fault code numbers (not "that crank code I heard about", etc).
