I was told by my company that linears cannot be put in our 2002 Internationals due to the electronics. I've asked a couple of reputable radio shops if they can be placed in these trucks and the assured me that they can be.
My question is:
Can linears be put in these trucks? (Texas Star 350)
I can't help but to think that these radio shops may not care about the truck and is more concerened about making the installation fee.
Thanks for any replies |

Ive heard that running power can blow a diode out of the trucks computer. since the computer is solidly encased in plastic and unaccessable for repair you get to eat the cost of a new computer because of a 49 cent part. on some trucks i've heard that it can cause failure in elecrtonic brake systems |

Fun guy is correct. And if you install a radio when the vehicles manufacturer says not to you could very well void the warranty.
Many new vehicles have computers that can be damaged by signals generated by 2 way radios. And if they go poof your vehicle can start to do strange things.
Check with your vehicles local dealership and have them send you some information. |

Funtimebob,
I have actually been witness to the result of a linear causing electronic brakes going out. While on a run from Los Angeles to Orlando I stopped at the Ontario truckstop and there was a canopy over the service area that had been taken out by a rig that had it's electronic brakes taken out by the operator of another passing truck that had a linear probably strong enough to give the operator brain cancer LOL! |

I don't believe that a amp can knock out the brakes on a semi. The electronics don't stop the semi, air to the brakes do that. You can hook the box up to the batteries and a 350 Texas Star should not hurt a thing. |

Its not just the brakes. Its the whole truck! You would be suprised by how if he had just the right amp and truck combination that it could kill the motor. |

im sorry to say that it is possible to mess up a trucks electrical system i did it to a guy, im bad didnt mean too, i keyed up a 1000 watt box as i passed a guy on route 81 here in ny and his truck sputtered and quit at 65mph!!! i didnt mean to or even think that anything like that could happen!! but you might be able to shield the computer as i had to on my buick after 3 computer s replaced that is. i tried it with tin foil worked egh. then i actually made a mold melted tire weights from lead and made a sheild for the computer and it worked very well!!! maybe an idea for you but if not just put in a ranger 2970 or something like that. might be a lil less problem for you. good luck |

Thats right it is possible. I know somone with a ford fiesta and a palomar 600, on high it kills his motor!

I drive a truck and a 350 will not shut down the motor on a new truck, if you hook it up to the batteries, or mess up the brakes. 10-4 |

I'vs seen a parmar250 shut down a GEO METRO moter. And at least one car company will not honor your computer warntee if you put a 2 way radio over 100 watts in the car..... A bunch of lawsutes over this one. Sometimes it pays to drive a 79 CADDY. |

I've worked on two Cat powered trucks that an amp was installed in that damaged the computer. Big bucks to replace complete computer.
As far as the brake problem, they are also affected under special circumstances. Yes, air pressure does the work in applying the brakes But, electrical impluse directs the amount, if any, of air pressure needed. The sensors in the ABS system direct this air flow.
Case in point, I pull two 48' trailers equiped with ABS systems. When the jumper from trailer [electrical pig tail] pulled out on a tight turn the second box had no brakes.

Jim:
It is possible to fry the computer in a big truck. However it's also possible to run a big box too. From my experiences, I've found that you must GROUND every piece of radio equipment. Keep your coax as far from the engine & dashboard as possible (run coax along the headliner if possible). Make sure your antenna has a good ground. Also as an added precaution you can try the above mentioned aluminum foil trick (wrap the brain box in tin foil).
I'm no expert, but I've found that stray RF and the poor shielding of the truck's brain can cause it to go bad and fail. I'm not sure how to stop stray RF but I guess if you use top quality coax (like Belden, etc) and follow the tips I mentioned you should be alright. |

I drove a Mack for a short stint.I had a cheap no name cb and a galaxy 80 linier.Everytime I would key it with the linier on the truck would die.I had to turn the key off,then back on and it would run again.
Quite entertaining! |

Try next time using a decent radio that has been properly matched to a KL60 or 203. As long as that's done in conjunction with good coax and swr below 1.7 it won't even flicker any electronics in the truck.
When running a radio not matched to an amp, commonly it is overdriving the amp with carrier causing stray rf all over the place, hence the electrical problems (referring to the post before this one).
