RE: [TG11] DragonFly 4S Will Not Power Up
I had a problem with my unit Dragonfly 7, I thought is was the power. I got oxidation on the terminals and the unit wouldn't power up. I tried to measure the output at the connector pins 4 & 5. The probes on my meter did not actually contact the sockets on the connector, I had to use paper clips to actually make the connection. I measured the voltage at 12.4 volts, unit still didn't power up. Turned out to be high impedence due to the corrosion at the fuse box. Cleaned the terminals well at the fuse box to fix the issue.
Before removing the filter you can cut the black case of the filter carefully and remove it and then cut the opaque potting off the bottom to access the pwb and measure the output side of the pwb on the bottom at the access points. I thought that my unit was broken but confirmed that the unit was good by brining it back to Raymarine to check it out. The folks there are great, they put my Dragonfly on their test station confirmed it was good and undated my software. I can't say enough good things about those folks! |
