Hi we have this truck that has damaged 4 H bridge cards over a period of 6 months. Each time we replaced it, the truck works sometimes for a few months in this instance 3 days.
We have checked motor for earth and shorts all checks ok. Battery is ok and no earth leakage anywhere on the truck.
Does anybody have experience in this type of truck with this fault which keeps taking out the H Bridge card?
Any input would really be helpful.
Cards were replaced from TVH, some were repaired by myself, others were off a truck which had been dismantled.
