using 9 volt batteries in Tejon

Texas Ted

Just wandering if using Two 9 volt batteries in the Tejon would hurt it in anyway. Bought a used Tejon that had been sitting in a Garage for 2 years with the batteries left in it. I cleaned it up the best i could, using baking soda to counter act the acid from batteries leaking and put a new set of batteries in it. It just doesn't seem to be working correctly. I was thinking of just getting rid of the double A packs and putting a 9 volt battery in each side if it won't hurt the detector. I hate to send it in to be repaired for the batteries being left in it if i can do a quick fix myself.
 
If I were you I would send it for repair, why risking?. I don't remember of someone doing that mod
 
I had a older golden sabre II once that had two 9 volt batteries in it instead of a battery pack. It worked no problems. Thats why i am curious. If it is not going to hurt it i was going to do it. just hate to ruin a good detector trying it and not knowing. If nobody has tried this then i guess i will send it in to have it refurbished.
 
I think that is a wise decision. If the battery compartment/wiring is the only problem, that should be an easy replacement for the factory. Some of the older machines were designed to run on 2 - 9volts whereas the Tejon is designed for 8 AAs. Depending on how the circuits are wired you're potentially comparing 18 volts against 12.

i think they operate at around 3 or 4 volts. They have something that lowers the voltage down to 3 or 4 volts. if they operated at 12 volts the batteries would not last 20 0r 30 hrs. I just didn't know how many volts the thing they use to kick back the voltage could handle, and can't find any information on it.
 
I have had pretty good luck cleaning dirty contacts from battery leakage (lots of practive from cleaning my son's musical toys he has bought at yard sales over the years) and my thoughts are that you have cleaned things up to where it should operate as it suppose but have a feeling that there are other issues with the detector, just my thoughts of course.
 
Call Tesoro and ask how much the repair will be for a leaky battery box. 928-771-2646

Any modifications that you do yourself will greatly decrease the resale value.

Trying to save a few dollars gets expensive sometimes.:)

Your probably right SkiWhiz I cleaned the contacts, They don't look like new they have a dull color but it is operating so it is making contact. I know there is probably something else wrong with it cause it is not opereating like it should. I have owned several of these over the years, and know how they should function. I was just hoping it was something to do with the battery terminals not being shiny new, but deep down know that isn't the problem. I guess i was just debating on having it sent in and gone over throughout and hope they see the problem and fix it, or just use it for parts. I got a good deal on it $275 but really thats a high price to pay for parts. It works just not as good as others i have had. I will probably just send it in. thanks everyone for your thoughts. I have a vaquero, and a cibola also so it isn't like i will be without a detector to use.
 
Please let us know if you send it in what the cost of repair is and any other problems they find with the unit.
 
JMHO I think it would be money well spent for one of the best Tesoro units made Wish I had never sold mine ole well lesson learned good luck on your decision
