Re: [tracker2] DR-135 Power Issue
Even though you don't like poking around inside, see if you can trace the power in and then look for any large traces on the PCB. See if you can trace those along and look for any kind of internal fuse or sacrificial resistor. There is always the chance that the fuse outside is ok, but there might be one inside, on the main PCB that has failed and most likely saved the radio from further damage.

Subject: [tracker2] DR-135 Power Issue

I bought a new car and yesterday was pulling power wire, a connection to my Nuvi 350 GPS and an ignition key interlock to turn the radio on and off with the key despite taking power directly from the battery. This wiring set-up was to replace simply running the radio from a cigar lighter connection I had been using the first few days of having this car. Everything was working properly until I made the switch-over to the new wiring. At that point my Alinco DR-135 / T2-135 2 meter radio wouldn't power on. I connected it to another power supply in the house and it still wouldn't turn on.
Fortunately I had an identical radio running in the house. After making sure I had the wiring in the car correct I connected the second DR-135 and all is well and it works as expected despite having made no changes to my original wiring configuration in the car. Something odd happened. I gave the first radio a quick once over and have 12v power past the last fuse on the power line and even changed fuses "just in case" the fuse seemed OK but was not actually passing current. It still doesn't power on. Poking around inside the radio gets a bit beyond my comfort and skill level to track the problem any further.
Is anyone familiar with any issues regarding the DR-135 and sudden power problems? I ask here as there are a lot of DR-135 / T2-135 users on this forum.
