Used to have the problem with my jeep. Was running RG58U as a jumper from my amp and switched to mini 8 coax and that solved the problem. |

You have two options....
1) Get rid of the power...
2) Find the computer in the truck and wrap it in foil. There are two type computer housings , metal and plastic...You have a plastic one...

check your alternator, I've got a 2970dx, and a davemade m400 and they both do fine on high power in my stock dodge ram with one battery and a 120 amp alternator. |

307 has the answer.....It should not have anything to do with the alternator or battery as it is a diesel..it only needs a small amount of current to keep the solenoid open for the fuel pump. The computer needs to be found and shielded |

Thanks to all, will try 307s advise in the morning. If it helps even a little,then I'll try a lead wrap with the foil. Life with radio was never this complex in the 70's. thanks 307& all! |

The foil is a good idea, but it may be a band-aid.
1. I think it's a big mistake running that 93T into a 250!!???
2. It really sounds like you have either the radio poorly grounded otr the antenna poorly grounded. RF travelling through ground is the most common cause of ECM interference. What kind of antenna? How is it mounted/grounded? Coax good? |

id look into shielding the computor definatly needs to be done. tech 671 also has a good point as well check your grounds. nice big, short grounds are the ticket. |

I've got a 2000 F350 SD diesel with a 2970 going into a xforce 8 pill and it doesn't kill my truck. I had problems when I had the Western Diesel chip that used a wire from a switch to the ICP sensor on the left top of the engine, keying that thing then would kill the engine.
That wire served no purpose, it can come off.
Do you have any sort of performance chip in there? Also check you're voltage when you key the radio and then key with the amp on as well, I'm with Tech671 on that one I thought the Pal 250's only like about 2w dk going into them and probably not a 100w swinging into it. But those diesels don't like less than 12v and you may be seeing a major drop in voltage when you key both of those together. |

Hi guys, been working,slow answering. Shielded both computer boxes,no change. Moved radio to another truck,wilson1000 roof mount,didnot move it. Truck still loses 300 rpms, with 4watts in pal on low motor dies. I do have a chip on truck,dont know what kind. Tried firestick 2,even tried isolating it to battery ground only. No voltage drop(used diff truck)rf from ant. is problem. dont need amp but still have rpm drop on med and hi when idle. |

How is it with just the radio? |

Whew! It may be the idle control from the GOV sensor , I give up...

just radio,idling lose 3 to 400 rpm on med and hi. On the road dont see drop just hear a little change. Radio talks great,tech here set mod. and the swing is unreal. Just not sure if I am hurting truck,and like everyone else I like a little edge. Thanks to all,Happy New Year!!!!!!!! |

My Galaxy 93T really runs great, but I have not used my Palomar 250 on it either, it really gets out great, I do not know who worked on it when it was shipped to me , but thank you to the Tech, it dead keys at 3 watts AM almost 3.5 and really talks , and makes it to the East coast,
thank you Copper |

Is the chip you have the one with a 3way or 2way switch in the cab? Mine did the same with the wire going to the icp. The icp is just below the alt on the upper front of the engine compartment. The reason I mentioned a voltage drop, the rf would affect the icp which in turn affects the pcm. My would do the same even when I was setting next to my semi truck running power. It would kill my truck as well. The chips either tie into the icp or map sensor. Check these two places. If you have the tripower chip, the wire going to the icp is not needed. Unhook it and see what happens when you key the radio and amp. Try the same with the map unhooked.
Just a thought, hope this helps. |

Jellybean this could be possible,but its like your speaking in tongues(way above my head)and I may have to have a shop help in that chip. I will try after new year and post results. I talked to an auto tech today,he said we could test truck on scope and when keying the radio it will tell me what is beening affected. |
