House had a massive power surge.
Took all the batteries out, fully charged and tested each one. All Dekka all good
Hook them al back up knowing they are 100%.
Meter on dash shows them dead, then starts flashing all lights on and off.
Pretty sure controller and or charger (possibly the motor as it will now barely move) got taken out with surge.
Fuses are good, batteries were taken out for the E4, charged then taken in to load test each one then put back in.
Tech question; How can I test these parts?
Where can I get a quote for replacements for INS. They will cover all parts and maybe some labor.
