We have been seeing people asking us to fix problems they are having with cheap conversion kits they sourced from the internet. They tell us stories that are truly frightening about attempting to take apart battery switches or create dangerous connections between components with little understanding of the consequences. For example, a battery that has been tampered with is a danger to property and person. Whole house fires have resulted.
Unfortunately kit manufacturers sell their wares suggesting that their kits can be installed by anyone. This is a dangerous situation. In our shop we can only warranty conversions that we have installed ourselves by a licensed electrician and machinist. If someone chooses to buy an inexpensive kit over the internet and install it themselves they do so at the risk of their own safety.
