Question about Motorola Radio Communications
We had to install a new voltage regulator in the alternator in one of our fire trucks. We can now not key the Motorola 2-way radio in our truck without the voltage spiking. Do you know what could be causing this and is there a way to block the radio transmissions from affecting the alternator?
Hi and welcome to FixYa,
Your described problem indicates that the RF from the Motorola is being received by the electronic regulator of the alternator and is erroneously factored in as sensor/triggers. Simply stated, the RF causes the regulator transistor to conduct more allowing higher voltage output. There could possibly be two ways of addressing the issue: regulator/alternator side and/or the Motorola side. Things that you could try:
Pls post back results. Good luck and thank you for using FixYa.
