Excal 800 coils

[Steve in PR]

Thanks, Art. I will give it a try. Went hunting today and it didn't skip a beat. I turned it off tweice, let it sit and turned it on again and no problem after 3 hours. Might be a problem finding a day I don't go hunting but I will take those measurements and let you know as soon as I can.

OK.......

Hope you can manage OK. Sometimes forget that everyone else has not used test equipment as much as I have.

Something else you might do while waiting for a chance to check it out good is to disconnect the pack when not in use in case the detector is draining it, and see how many hours you get before it craps.

When you hook it back up, if it's bad after overnight but had worked the day before, then it's a good indication of a bad pack.

Plenty of ways to skin this cat.

I don't know how the Excaliber goes together since I dont't have one "YET" but i had a Garrett seahunter. Iknow on the rechargeable batteries the way I got the best results was to charge the battery and go hunting. when I got done I would leave the detector on untlil the batts were almost dead, then slap it in charger. Never had a problem doing this.

Also where you have any connections you should be using Dielectric grease, you can pick it up at radio shack and most marine stores. This will just about cease any kind of corrosion and also helps with expanding and contracting contacts. When it gets cold metal contracts and you lose connection the grease helps to conduct the connection. I work in the marine industry and people just don't understand that salt air is just as bad as salt water. Also the heat (especially here in Miami) is terrible on batteries, the heat just sucks the juice right out of a battery. You don't believe me stick a flashlight with new batts in your attic and see how long it lasts. I did alot of attic crawling installing alarms for ten years and heat is a battery killer.

Also you may want to look into a different battery pack. I know they make a waterproof rechargeable for underwater lights, it is 12V and is a great pack. I'll check at my local shop,the owner is a real inverntor nut and knows a lot about the batteries they use.

Hope some of this helps.

While most of these small charger or power supply modules either work or they don't, there is always the chance it is putting out less than normal voltage due to a short in the transformer secondary winding, or a bad rectifier.

If you can check the voltage at the output connector you should see almost 19 volts. That's what my nicad charger puts out under a "no load" condition.

If you get something close to this, then you have ruled out the charger.

the odds of that happening are slim to none.Get rid of your Nicads or use as a spare. You should always have at least 2 or 3 pods.Have a NIMH battery pack made and your troubles are over.You can top up your charge at any time without memory and get many more hours of use depending on MAH of battery.And also get rid of the half a day or more wall charger and buy a MAHA charger for very fast safe charging and cut your time of charging to a few hours at most without fear of overcharging due to it trickle charges when it gets to full charge and you are set and this charger can be use for packs or AA or AAA batteries in numbers of 4 or 8 at a time. Good Luck Walter
