Why is my panel van emitting heavy black smoke, has no power, and has high fuel consumption?

Sounds like it is running rich. Unfortunately you did not indicate a year, make, model, or engine size. This makes it nearly impossible to help you solve this problem. Also if it is a later model vehicle the check engine light should have come on. Have you checked for codes?

sure , stronger battery can give you more RF signals (it's a radio transmitter, and as such will be weak if battery is low.)

02 ford e 450 ambulance every time we key the radio it shuts off

I assume you mean the Engine shuts off when you key the radio. Two possibilities. One is the radio is drawing too much current from it's circuit (which could be improperly connected to a critical wiring circuit instead of an accessory or direct to battery) OR The RF signal is causing severe interference with the engines electronic controller. in either case, see if you have a "low power" setting on the radio. key it up and see if that has the same effect. If all goes well you know your radio is certainly the culprit in either the power or RF side.

Some two way radios are rated to 100 watts, thats a lot of amps of current when you transmit. These radios usually have a main power leads that should be connected to the battery or battery source direct (not spliced into some wiring). IF RF is the Issue, you have a problem with your coax between the radio and the antenna, or the antenna is much too close to the ECM. IF the antenna is mounted on top of the vehicles metal roof, the coax is almost certainly the problem if RF is the issue. look for bare spots or poor connections

Rf signal killing battery

Newer cars do have a massive amount of memory in them at all times. (radio presets, every computer, shift patterns, Clocks, OBD2 stuff) In addition to this problem they are started electronically by the the cars computer. It needs to see enough voltage to engage the starter. If you check your owners manual there are some fuses the manufactor recommends you pull if your are going to leave the car sit for a period of time. Also I would recommend a new battery with lots of cold cranking amps. Buy a high priced one. You get what you pay for with batteries. I have never heard of RF signals being a problem.

I put a differnt key by mistake in the cadillac by mistake and now the car will not start with the original key?

The keys have RF chips in them. It's possible that it's a 'fail safe' security featur for your car to prevent theft. Try disconnecting the battery for 30 min. to reset the electronics, reconnect the battery and retry.

What size battery do i need for my 2004 ford escape?

1. Look in owners manual under specifications.
2. Go to Autozone or Advanced Auto websites, enter car year, make, model, etc. and put battery into the"search" window and they should list the possibilities.
3. Go to Walmart, Costco, or any other big box store and they will have a battery display with either a book or an electronic catalog of the battery types for each make and model car

Factory security system draining battery

There have been problems with electronic alarms draining batteries and locking out etc caused by RF interference.

This can be from Phone transmitters, WiFi hubs or other sources of RF energy.
Basically - the alarm is staying awake reading every piece of interference - and after a number of attempts locks out.

You could try contacting the manufacturer - to put the system onto a different frequency, or reduce the sensitivity by shielding the aerial of it - or find the cause of the RF problem.

Contact here again if this doesn't solve it.

Battery again

I don't know the exact size of the OEM battery's amp rating, but that seems low compared to most batteries. At the minimum, you want probably 600 CCA (it's a decent-sized car with a lot of electronics in it), so I wouldn't buy below that rating, especially if you live where it gets cold in the winter (that's where you really need the higher CCA ratings).
