no speed limits here
#1. I wondered what that was too. The green paint obscured the transistor's heat sink.
DC/DC converters are often based on switching regulators which use an oscillator, a high power transistor, and a coil. The 12V current is switched on and off by the transistor and the energy is stored in the coil. The voltage can be stepped up to a much higher level this way.1. high powered transistor.
2. Transformer. Vacuum Fluorescent display require high voltage to work, so it's most likely stepping up an AC voltage signal. Note: Transformers only work on AC signals not DC. This also means that somewhere in the circuit it is converting DC into AC.
In case you're still looking, there's still the old one, but I've also created an updated, easier to follow mirror of it here:HYPERSONIC007 said:what happened to the 3si wiki writeup on this??
I posted this in your other thread, but figured it might help those in this thread as well.It looks like R55, R56, R64, R66, R67, also IC3 have a couple black terminals. Thanks for any info.
Anyone with any insight on this problem?I'm having a problem with my a/c as well. I had a climate control go bad, so I bought a new one. It's good, I checked the capacitors. My problem is with this one plugged in the a/c still wont come on. The lights for the buttons on the climate control light up, but the center face will not. Also the unit does not beep like it should. Anyone have any ideas? Or a wiring diagram for the unit?
Do you mean the black box that's below the climate control? Kind of between the climate control and the radio? Or the metal thing that's directly behind the climate control. I looked and couldn't find anything a wiring diagram.If the cc isn't working at all try looking at or replacing the other controller. usually What happens is it continues to work but has no display. Yours sounds like maybe the controller behind It.
