I think I broke my Ace 250's 9x12 coil :rage:

[treasurefiend]

I think this because I went out hunting today and I couldn't get a solid signal at more than 4 inches to save my life!!!!! 4 inches and less it works fine, but beyond that it jumps around like crazy. I tried it with the sensitivity all the way up and medium and and on 1 bar, it all the same result. I was hunting with another guy and he found 9 wheat's at about 6 inches and he didn't have any trouble with the signal jumping around erratically. I looked at the bottom of my coil and it has cracks all over the place, even in the inner part of the coil. I have no idea how they got there. I am always careful not to bang it too hard and I have never stepped on it neither has anybody else. The only thing that I could think of is I keep my Ace 250 in the trunk of my car, and it gets super hot during the day, maybe that cracked my coil. I am at a loss for words. It looks like I have to start using the standard coil that came with it. What really gets me is I only started to use this machine back in March of this year.
Also starting like 2 weeks ago, all of my wheat cents have been regestering as dimes...

Lesson to all, buy the coil covers and use them & don't store your metal detector in you trunk of your car...

Uncle Willy or Awhitster or anybody else ever have this problem?

You can bake cakes in those hot trunks!

It is way eay too hot in the trunk. Consider the catylytic converter reaches thousands of degrees plus the heat form the muffler and tailpipe and it all goes to the floor of the rear or trunk. so even not counting how hot it gets from the temperature it will ruin your detector.may already have.

 

[khouse]

You better try the standard coil to see if it is the coil and not the detector.

 

[Uncle Willy]

Sounds like the resin in the coil may have been over cured and crystalized. Contact Melinda at Garrett. You might be in line for a new coil for free. melinda.harper@garrett.com

Yeah they shouldn't be left in the trunk in blistering heat, but even that shouldn't crack his coil as he described. Temps in the trunk can hit 150 degrees plus. We don't have that problem out here plus my vehicle is a van and my tectors ain't confined in a limited space.

You didn't break the coil. I had the same problem with mine. I called Garrett and the gal there actually did air tests on one there over the phone and compared them to what I was getting. It was the coil. SHe said just send it back for a replacement. I ended up returning it to my dealer and got a cedit for something else. The coil is just too heavy after awhile.

Speaking of Catylytic conveters I need to get mine replaced ( or cleaned out, which is illegal ). My little car that usually gets 27 mpg in the city and 38 on the open hig way is down to 18 in the city and 30 on the open high way. You can actually smell the sulfer order!!!!! I replaced the plugs and wires and that helped a little. Come to think of it I need to replace the fule filter too just in case.Gas just hit $4.19 a gallon here. I bet it will be up to $5 before the end of the year.

Yeah if you could burn all the gas that goes out your tail pipe you'd be getting 200 MPG. That's what the converters do - burn that excess gas. When I was a young pup we used to install spark plugs in the end of our tail pipes hooked to a Model-T col with a two-way switch. At night it was really spectacular when we flipped the switch and a four foot long blue flame shot out the pipes. With twin pipes it looked like a jet going down the road. That blue flame was fueled by the 80% of our gas that was going out the tail pipe.

Back in the thirties a Canadian by the name of Charles Pogue invented a carburetor that got almost 100% combustion and produced 200 MPG but the oil companies put him out of business fast. His patent is still on file at the Patent Office and anyone can build one. Some have over the years but were quickly bought out by big oil.

I wouldn't be quick to replace the cat converter.. Sounds like you have emissions
control problems, or need a better tune up, etc..
How old is the car?
It's much more likely that you have a engine problem, rather than cat..
IE: lets say the coolant temp sensor flakes out.. The engine will think it's
cold all the time, and will stay in "open loop", and run way too rich.
Replace the sensor, and all will be back to normal as the computer will
see that the engine warms up, and go into closed loop. The engine will
run much leaner, and you won't be spewing all that excess fuel into the
cat, which can ruin in over a long period of time.
Not saying the temp sensor is actually the problem, just explaining how
a simple part like that can whack out the emissions system.
Unless a cat has been abused with a rich fuel mix, lots of oil, etc, they
last a *very* long time. They can last the life of the vehicle no problem
as long as the engine systems are kept up to par.
Also.. Many aftermarket cats are junk compared to the ones used
by the car companies.
Anyway, with a problem like that, the cat is usually the *last* thing to
consider, and the last resort.
Sounds like you are running too rich with the sulfer smell. Thats not a
cat problem.. Thats an engine problem.
When taking an emissions test, many will bomb the NOX tests.
That is from excessive combustion temps due to improper timing,
excess carbon buildup, or running way too lean.
Fix the real problem! Many change the cat as a "band aid" fix without
actually fixing the real problem. All that does is usually get you an
*inferior* cat, and with not fixing the real problem, it's quite likely to
blow a worse score than the old factory cat. No joke.. I've seen it
happen many times.. Again, most 3rd party cats are junk and no
where near as good as the factory cats. Also the factory cats
have a long warranty on them.. If the car is not too old, it could
be covered.

As far as the coil... Dunno if high heat would do that or not..
I'm not too keen on testing out the theory...
I am an advocate of coil covers though..
I use them on all mine, and all my coils still look pretty
much like new if you yank the covers. Cheap insurance I think..
