Hey Guys,
I have a bit of an odd problem........
My car has 2 Simoco 2-way radios installed that I use for work. Both have a power output of 25w. One radio is 136-174mHz, the other is 450-500mHz.
I had a faulty alternator replaced with a brand new one last week.
Now if either of the 2-way radios are keyed up with the engine running (no problems with the engine off), the alternator warning light comes on, all the lighting on the car brightens and the car either starts to idle all over the place, or if driving engine power drops! It actually blew a headlight bulb tonight because of this problem.
It seems to be related to the RF power the radios emit. With the antenna's unplugged, the problem disappears. From what I can gather the RF must be interfering with the new alternator in some way. I had absolutely no problems at all with the old one.
None of the wiring for the radios was touched, except for being disconnected from the battery while the alternator was changed. The cables are connected to the alternator firmly and the earth strap between the engine block and chassis is fine. The coaxial cable for both antenna's is in good condition with no nicks or cuts anwhere. Any ideas on how to rectify the problem???? It's got me stumped.
Thanks
Daniel
