Re: Palomar 150watt bi-linear amplifier for c.b....
OPEN IT UP THE SHORT MAY BE WERE THE 2 POWER WIRES COME TOGETHER AS THEY ENTER THE RADIO THIS HAPPENS ALOT OR DESOLDER ONE OF THE WIRES OFF THE CIRCUIT BOARD AND CHECK FOR A SHORT ON THE WIRES AGAIN THIS WILL TELL YOU ALOT IF IT IS THE WIRES OR IF IT IS ON THE CIRCUIT BOARD GOOD LUCK

sniff around inside ,see if there is the smell of burnt wire or other componants.If it turns on see if there is a componant that starts to smoke.If it does change it and see what happens.this is called trouble shooting.
If its in a car or truck use heavy gauge wire to power it. I use a 3ft jumper between the radio and amp. Should use a grounded antenna system. Not a "MAG MOUNT" type. Those can "feed back" rf to your radio and cause problems. If using in the house, a large power supply will be needed.I own a palomar elite 400 hd.It uses every bit of my 30amp power supply. Your hd amp should like the hp radio.
Not if the power output from radio to amp is set correct and the jumper for coax is correct length and there is absolute perfect match between them and the antenna used. Afterthought: also the amp better be connected to something big enough to power it.
First of all you only have the Power wire Red, and the ground wire Black to connect for 12v DC to power the unit. If you memory power it is usually connected to a constant power source such as the cigarette lighter or continuous 12V dc powersupply off of the battery. These are the only connections that should be connected to provide power. Since the unit will not turn on I suspect that the CB's power supply and regulator have been blown. Another possible choice is that the radio was working and someone removed the antenna cable and the the RF power amplifier malfunctioned taking the power supply and regulator with it.
To solve this problem, check the voltages on the wires before connecting them to the radio (these should be the 12 volt power off of the radio circuit, and the 12 volt power off of the continuous 12V connector (or the cigarette lighter). These voltages should read 12V.
Connect the CB with it turned off and measure the voltages (should be 12V)
Turn the radio on and check the voltages (should be a little less than 12V)
If the radio does not come on then the internal power supply of the radio might be defective (In this case I would advise taking the CB to a qualified radio repair shop)
I hope this helps
