I have a boat that was previously wired for a PG-1000. There are 3 wires where the old heading sensor used to be.
1. single pair for power +- 12V
2. AD10 cable to plotter
3. bare ground
I'm replacing with a PG-500. The PG-500 has a 7-pin connector instead of the old 2-pin that supplies power.
I made up a new 7-pin connector that supplies 12v +- on pins 5&6 and connected the bare ground to the exterior case screw. However, when I turn on the breaker the PG-500 does not power up nor respond to any button presses.
I see that pin-7 in the wiring diagram has a GND connection. This appears to be connected to the external case ground also. Do I need to supply an additional ground connection on pin-7 in order for the unit to power up or do I have a defective unit? Any other reason it wouldn't power up straight away?
Thanks!
