when I connect the hose to add to the system the guage is in the red does this mean I have to much in it already

What gauge? The one that can with a can of 134a? Was the system turned on at the time? Was the compressor running? Assuming it is a gauge on a can that has 134a in it, realize the gauge may not be super accurate. It should be connected to the low side service port. If the compressor is NOT running, the reading you get here will be higher than if it is running. If it is running, the gauge in the red is an indication of an overcharged system, but there are other factors that can cause the low side to read high and produce poor cooling in the cab.
I bought a can of 134a at w**-mart that had a stop leak, oil, and dye in it. It also had a hose and a gauge, so now I'm an AC pro!
Need more information..
1. Why are you adding refrigerant?
2. Does the compressor engage when the system is turned on?
If it doesn't come on, you can try to jump the two wire cycling switch on or near the accumulator,if it still doesn't come on you most likely have a worn clutch..You can turn the system on and tap the outer clutch inwards (very carefully) and if it comes on, you'll need to remove a shim.. That is the most common problem on those ford Scrolls.. If it comes on by just jumping the cycling switch, you may need a new switch..
Pressures are needed to properly diagnose the system, and the one can gauge doesn't do it.. Hope this helps..
Freedoms just another word for nothing left to lose
Brother-in-law purchased one of these DIY kits, but decided not to try it so gave it to me. In testing that gauge against my NTIS standard gauge, was 15 psi off the nominal 30 psi level. Are you kidding? Plus the cans contained some kind of leak proof crap that can do more damage to your system than what its worth. Are you kidding?
But if you just connect the gauge to the low side port, are reading static pressure that would peg and wreck this gauge. Are you kidding?
Then the assumption is made, you are low on refrigerant. A very stupid assumption to make as complex as these electronic systems are today. Also see these commercials on TV where that idiot is a hero for his girlfriend, girlfriend is cute. Ha, if you really want to impress your girlfriend, learn all about AC and get all the correct equipment. LOL, my girlfriend was very impressed.
If you are actually low on refrigerant, you have a leak, have to find and repair that first. One thing about leaks, they are never self healing, just get worse. And typically never one leak, unless you are lucky. Are you feeling lucky?
I love the advertisements for vehicles on CraigsList that state "AC works great, just needs a recharge" .....
Last used car I looked at was just a tad low on free-on, believed that. Could see a rotted away high pressure line just inches above salted slush that was broken in two pieces. Wonder if that sealer could fix that?
You need to get it recharged and air filled inn it. If still problem continues contact an expert.
