When you start up, the P R N D display no longer shows and when you move it never changes gears so you're basically driving on one gear. It reverses. I had the car scanned and received the following prompts
P1750 Electronic Gear Selector Module: Very low control unit supply voltage
P1910 Electronic Gear Selector Module: Control Unit over voltage
I was told its the gear selector lever thats the problem but i've replaced it 7 times and either it doesn't fit or doesn't work altogether...
Im beginning to think the mechanics are using trial and error to decipher the fault so I need a second opinion. thanks
||| mechanics are using trial and error to decipher the fault .. really my Gear Selector has ben broke for five yrs now really if you cant back it up or go forward its not going to be any Gear Selector Module be more like the transmission

My 1991 honda civic Idle high and bogs when it takes off?
I have 1991civic with JDM D16Z6 engine and it idles high and when you take off it bogs then it picks up speed. I have checked the the ECU it says throttle angle, intake air temperature, electronic air control. I have replaced the fuel filter the injectors and the Idle control unit. When I take it itt bogs then it start to pick up speed it all most seems to get to much fuel. when i push on the pedel it bogs and when you press harder takes a couple of sec to start to pick up. I almost have to put it to the floor. If you can really help me you can call me 513-557-6276 my name is brian|||sounds like an air intake leak, check all the rubber hoses to be sure they are not cracked or broken and look for any hose that has come loose, replace cracked and broken hoses and re-install any loose hoses. (hoses and vacuum lines)|||it sure sounds like a vacuum leak, if u can check the oxygen sensor and the mass air flow sensor if "its equiped wit one" check all of your air intake hoses!
There is an electronic components is operated on DC power 48V.?
It is a kind of alarm management unit.It has the ability to control AC power components.Which are operated on 240AC.This input and output of the AC component are terminated on the PCB of this alarm management unit.
1.What is this component?
2.What is the advantages and disadvantages of a DC
operated unit controlling AC unit on the same PCB?
3.If the DC section of this alarm unit have a separated PCB and the electrical appliance with 740V AC supply also have a separated PCB,but is being controlled by a single cable from the DC PCB, what will be the advantages or disadvantages?|||Shade is correct, you can use a relay or SS relay.
Watch your PC board spacing. Keep 1/4 inch spacing for anything over 100 volts. For 740 volts, even more.
You may have trouble getting regulatory approval if the high voltage AC and the DC control is on the same PC board.
How did the AC get to 740 volts?|||If you want to seperate a DC and AC system you can use normal relays or solid state relays. Otherwise Triac or Thyristors. For DC to DC you can use opto couplers.
Make sure your board design or wiring is such that it is seperated. Always keep DC on one end and AC on the other.

How do I get my AC unit to restart automatically upon power restoration?
In the old days an air conditioner had a physical switch was set in the on/off position. After a power outage the AC unit would come on automatically. My problem is my new unit will not come back on unless you push the button on the infrared remote. Everything is electronic.
The problem I have is power is cut about 10 times a week and when I leave I need the AC to stay on to keep out mold and everything nice and dry.
How do I leave my home for 6 months and control the AC unit? Perhaps by computer and a modem?
Other than getting an old AC unit or hiring someone to stay and watch my house. I don't want to invest a huge amount to solve this problem.
Thanks|||Any electrician can rig up a relay system to add to your controls to do that.
He'd have to see the controls to do it though.

LP water heater - flame up inside of control box?
1990 Atwood water heater. The electronic igniter continues to spark after it begins burning. The flame travels back through burner to the nozzle, and flames up inside the entire control panel through the air regulator slip joint. I have a yellow flame and understand that it needs to be blue to eliminate carbon monoxide. Is there a part or parts that need replacing or do I need a whole new unit?|||you need to have that checked by a pro NOW before you start a fire or an explosion. SHUT IT DOWN.
Msd electronic ignition, should i install this or not, what are the pros and cons?
i was given a MSD 5 ignition control unit and on the box is says better gas super quik starts increased power and proven quality. i have a 1979 chevy 3/4 ton pick up that has a 350 engine and 400 trany and i was thinking about puttin it in there but im not exactly sure if i should.
plus this version was made in the 1980's. says it in the manual. not sure if old stuff like that would be good for it? but its never been used|||Unless your having problems with your truck I'd leave it alone.|||No. The HEI ignition system on your Chevy is plenty good enough. As the name indicates, it is already High Energy and solid state. It matches the impediance and resistance of your factory wires and standard plugs. These things make sense on an old style point system with mechanical slop and lesser firing voltage. List it on Craiglist and make a buck and skip the headaches.
