House has old wiring,going to be knocked down in 2yrs,1 part of lighting circirt keeps blowing fuse and knocking the trip off,every time I put trip on,in 20seconds it goes of again?

Put the wires safe from grounded chasis.Cech the main fuse (s) usualy under the hood.Try to start.Ceck after the function of the lights/turn signals.Rare:Back wheel may cross the trunk release,fuel pump wiring,stop lights etc.

Behind the door locking mechanism is a switch, it sounds like from the force a wire might be touching the inside of the machine chassis. Gain access to the back of this switch and check there are not loose cables or cables touching metal.
You should be able to access it by removing the top of the machine, remove the 3 screws and tap the front of the lid with the but of you hand to knock it back and remove it. With a torch look down the inside from of the machine to idenfiy anything loose. Alternativly remove the back of the machine and see of you can see it that way, as that model does have quite a large back access panel.

Keep your screws safe ;)

knock sensor problems arise from ---wiring --poor connections --knock sensor----insecure KS--KS incorrectly tightened ---wiring short to positive --wiring short to ground ---ECM
as you can see , there are more causes than the KS itself so care should be taken in the installation, tightening , wires and make sure that the area is water proof

I would guess it is a short> possible causes:
1) outlet: turn off breaker to outlet pull cover off and look for burnt or loose wires
2) dryer cord: take back metal plate off of dryer look for burnt or loose wires
3) heating element
4) check all internal wiring for burnt or loose connections

The breaker for the dryer should be a 30 amp breaker, and should only trip that breaker. If it is tripping the main on the panel then something else is wrong. You will need to pull off the panel the the breaker box and pull out the dryer breaker and look to see if it burnt, make sure the wires are tight on the breaker, you may want to try a new breaker also. Hope this helps Tim

you have low oil pressure, so adding oil will not cure the light, if the engine is knocking u have damaged the engine bearings and it will need to be torn down and rebuilt.

Are the bulbs out of the sockets and the fuse blows?
Take bulbs out and check again
Place one back at a time if fuse was OK with bulbs out to locate bad bulb.
Otherwise.......
Do this........if still needed with bulbs out and fuse blowing.
Put a circuit breaker in to replace the fuse of the same amperage.
It will trip off then back on.
Use a standard cheap magnetic compass........place along lighting wiring........the wire with current will cause the needle to jump as circuit breaker trips on and off.
Follow path of current to problem.....the compass will stop moving once past the shorted /grounded wire/connection.

pssible rod knocking.try pulling a plug wire off each cylinder only one at a time restarting only with one wire off, sometimes a rod will stop knocking if there no fire on the cylinder.old school method, some newer cars dont like this much it triggers some sensors and lights some times. or just take a wooden handle too your ear and too certain parts of the motor too pin piont the sound,keep away from moving parts

you have to figure out where there is a short in your wiring--follow wires, look for broken, missing insulation--if it started in lights, look there first maybe. Also check the connections of plugs. Good luck it may take some searching.

91 honda accord lx, fuse keeps blowing for tail lights. changed rear bulb sockets but still, same problem. fuse blows soon as i turn on the park lights. what can be the problem?

The code means there is a problem in the knock sensor circuit, that means the the knock sensor connector wire pins may have a problem, the wiring to the sensor may be damaged, or the PCM may have a problem, and of course the sensor itself, I have one question did you tighten the sensor to the proper inch pound setting of torque? if not this can cause a code to set because the sensor does not vibrate as designed to send a signal of a engine knock/ping.
