New Radar. Old Wiring

Upgrading from 1999 original equipment catalina 36 Raymarine Radar. Going with Raymarine wireless radar and chart plotter. Question is can I use the old power cables and save myself tons of work?

Re: New Radar. Old Wiring

Huh, no answers after a day? Okay, I'm not an electrician, but I'm going to take advantage of Cunningham's Law and claim that as long as the amperage requirements of the new radar are not higher than the requirements of the old one, and the old one works, you're fine to use the old wires. If the wiring can't handle the current draw, either the radar won't work, or maybe there'll be fire risk.

Hopefully someone who actually knows what the answer is will correct me :-)

I'll bet these guys can give you a decent answer.

Personally I'd be inclined to replace, rather then run my new radar on a 20 year old power supply.

How many amps/watts did the old one draw? And the new one? If the new one draws considerably less, which is likely, and there is nothing suspicious about your wiring, go plug n play.
