Anyone familiar with the electrical side of a jcb js 160? Had one that was running and operating then just lost all hydraulic control won’t track won’t do anything. Cut the machine off check fuses. The fuse for battery to ecu was blown. Replaced fuse as soon as the machine cranks and runs it blows the fuse. The machine will run but not operate. Smelt something Burnt coming from the ecu. Pulled it apart and it was fried on the inside. Checked both sides of all the fuses and none were shorted to ground. The fuse that kept blowing with the ecu hooked up had 24 volts to both sides of fuse with engine running I checked with out fuse so it’s back feeding 24 bolts to the fuse I assume because the ecu is fried. Just want to see if anyone thinks it could be a short somewhere or know anything to check before sticking a new ecu in. I appreciate the time.
