DC/DC Converter installed!
We finally got around to installing the Iota DLS-45 DC/DC converter this week. The unit was installed under the car in the tunnel that previously housed the gas tank. So we would not any issues with the converter turning on before the controller, we used a small contactor that is activated at the same time as the main battery pack contactor. We found out the hard way last spring that if the auxiliary battery is low on charge and the DC/DC turns on before the Raptor controller, it tries to charge the battery and pulls high voltage through the controller thus destroying the pre-charge circuit. So this time we did it right and ....no smoke!
One benefit of the work this week was that several new students were able to gain a better understanding of the vehicle schematic. Knowledge is power.
