Ranger RCI-6300F150 - Fan is not working ?

find the reason that the fan is not working
could be a coolant sensor problem, or relay problem

it could be several things......the rf final,bad mic,cold solder joint on the circuit board just to name a few.my suggestion is to find a good local cb shop,if no local shop find one along the interstate hwy most of the time they are located around or near some of the larger truck stops. tell the tech there what the problem is and go from there. good luck !!

have you tried it on all bands? still won't transmit?take it to a tech so they can fix it properly.

i have the same radio rci 2950. Ive had the same problem with mine,turns out with mine the processor would lock up,turning the radio off & on repeadly would clear the problem and the radio would work fine x-mit & recieve. the solution to fixing the problem is to replace the memory backup battery this battery works similar to a computer motherboard cmos battery when this battery goes dead all sorts of strange things happen to the radio wont transmit wont recieve or like your problem transmits continiously. the problem with replacing this battery is finding out what year & model your ranger 2950 is. the internet says only first generation ranger 2950s use the battery second genration & third generation do not use the battery. but the internet could be wrong. so i suggest getting a hold of (usa ranger.com) & give them a phone call or email and ask them about the year your radio was made. they may even service it for you or if you are electronic savvy you can do it yourself. the battery is located close to the main cpu on the front panel if yours uses a battery.

• Open your radio and look for a board with a plug going nowhere not even plugged in. Plug it in to the back of the frequency display. Some shops will not ship your e-chip because of how easy it is to convert they want to get paid for it.

those mics are supposed to work for most radios ,,,if your getting good audio reports,,i wouldnt worry about it ,,im thinking of getting one for my icom 735 radio,,how much did u pay and where did u get it,,,,if you are worried about damaging your radio,,get a hold of ranger ,,and ask them about the mic

Hopefully it's as easy as this carefully take the cover with the speaker in it off and look to make sure the speaker wire with the plug is plugged into the two prongs sticking up in the back right side corner it is a very tight fit though.Good luck Dan

replace memory battery its a CR2032 battery Radio Shack and Walmart has them from $3.65 to $5 in price.

Hello, Just offhand I'd say you have a bad solder joint on the main circuit board. Without more info, I can not tell you where to look,,,,, Mechanic
