Hi my name is***** will be glad to help. Check all your battery to starter connections and also be sure the batteries are hooked up correctly. POS to POS and NEG to NEG to keep 12 V. If ok then check the LVD module/breaker as it may have tripped which protects the ECU's from voltage spikes causing damage.
LVD is behind the passenger seat side panel. Use a coin or screwdriver to remove
ok sounds good. I am leaving to a family gathering for the eve but will reply back on my next login late tonight if you need more help. We can post back and forth as needed
Thank you for the update.... So the chassis has been modified.... It is possible that some changes in the electrical have been made....
