02 ford e 450 ambulance every time we key the radio it shuts off
I assume you mean the Engine shuts off when you key the radio. Two possibilities. One is the radio is drawing too much current from it's circuit (which could be improperly connected to a critical wiring circuit instead of an accessory or direct to battery) OR The RF signal is causing severe interference with the engines electronic controller. in either case, see if you have a "low power" setting on the radio. key it up and see if that has the same effect. If all goes well you know your radio is certainly the culprit in either the power or RF side.
Some two way radios are rated to 100 watts, thats a lot of amps of current when you transmit. These radios usually have a main power leads that should be connected to the battery or battery source direct (not spliced into some wiring). IF RF is the Issue, you have a problem with your coax between the radio and the antenna, or the antenna is much too close to the ECM. IF the antenna is mounted on top of the vehicles metal roof, the coax is almost certainly the problem if RF is the issue. look for bare spots or poor connections
