The jury is still out, actually. What did LazyDays do?
1) They ran a ground line from the brakes all the way up to the vehicle connector. (The factory had only run a brake VOLTAGE line to the brake system but just grounded off that to the chassis) The position of Lazy Days is that THIS was the root cause of the failure.
2) They wired each output from the converter module to control individual fuse-protected relays that activate the outputs.
Why is the jury still out? Over the past year, Lazy Days has “fixed” this failure nine times only for it to pop back up. The number of connections/disconnections between the last two failures was approximately seven times. THIS time, it’s only been four and I honestly can’t tell you when I’ll be 100% confident that the actual problem has been resolved.
Note: Someone suggested putting in a smaller fuse. The problem was never voltage (current) coming from the battery (supply side), which had the factory converter fuses installed. The problem was a spike backwards into the converter module outputs from the camper, we believe. Putting smaller fuses online from the supply would not have addressed this failure, in our opinions.
