When i turn My Solara DSC VHF radio on it no longer beeps . I cannot hear any squelch or pick up any channels. Is this my speaker that has gone.


To test a speaker, you'll need either a digital multimeter or an analog multimeter that can read measurements of resistance (Ohms)
First isolate the speaker from the amplifier (meaning, remove the wires attached to the speaker terminals).
Set the meter to Ohms (Omega symbol).
Take the meter test leads and place each one on the speaker terminal (make sure the test leads do not touch each other)- there is no polarity to this test so it doesn't matter which test lead goes where on the speaker terminals
For an 8-Ohm rated speaker, you should get a reading of about 6-7 Ohms (approximately 15% of the speaker rating)
For a 4-Ohm speaker, around 2-3 Ohms
and for a 16-Ohm speaker, about 8-Ohms
If you can an infinite reading (make sure the test leads are not touching each other) other wise, if the test leads are not touching and you get an infinite reading, there is a short in the voice coil; speaker is defective.
OL reading on the DMM, or O Ohm resistance on analog meter, broken wire connection inside the coil= open voice coil and is defective.
If you get the proper reading on your speaker, the problem IS NOT with the speaker

I have a 1971 Suzuki t350 bad stator Ideas?


Being a resistive coil there are pass/fail values for that assy. Given it's age, a re-wound unit will restore functionality if that is in fact the failure causing your problem. Find test values, and determine if it is in/out of spec. There are stator rewinders, prices and reputations vary. But it can be done for reasonable money spent. It is also possible to increase the output of the unit when rewound, some can be done some can not for various reasons.
Do a search on stator rewinding, and I believe you will be well on your way to solving your problem.....Good Luck

How much is the driver and where can i get it from asap


if you hurry this one is $60 http://www.bracesinfo.com/store/Electro-Voice-woofer--EVS-15SF-220697631956.html
or you could go the re-cone route which usually run $70 for that particular driver.
or just run a search on google for EVS15SF the exact driver for the Zx4 cabinet
they are in abundance, a lot of DIYers use them in floor monitors.

Faulty vhf cb radio


i would suspect a defective audio power amp inside your radio. if you have electronics know how, disconnect the speaker and test with a multimeter for continuity just to be sure. i might just be a dead speaker.. good luck
