I suspect this sounds like an automotive type question? So here we go as ill stick to the basics! All hookup wires and test leads should be inspected for? Firstly a visual inspection for any wire corrosion such as a thick green/white buildup of gunk on positive wires/connections or leads and also battery posts, which will either cause a break in the wire or an increase in resistance for which current to flow, thus a loss in some or all power! Secondly a more hands on approach to locate broken, chaffed, disconnected or open wires and test leads by manually moving them by hand while inspecting them visually and listening for a any cracking which would indicate a hard wire coating and could easily over time cause an unintentional short to ground (blown fuse...etc.) Lastly if all else fails invest in a DVOM (Digital Volt Ohm Meter) and obtain a wiring diagram specific to your vehicle and read the instructions and go from there as this is more than just the basics and an entirely new one for me to answer...
This is one that should be left for a qualified person. As the job can effect life and limb a permit should be taken out and the job inspected. Failure to do this can leave you responsible if someone should get hurt due to faulty wiring or practices. Sorry, get an electrician and insist he takes out a permit and an inspection is done.
Easy as one,two and three. There are four primary wires coming from you service panel.(provided you have three phase service) you can check by looking at the weather head on the roof. if it has three wires you have single phase but if it has four then you have three phase. the hot wires will be black,red and brown. the neutral will be white or green. the welder should have a manual that will give you the lead phase wire(most likely black to black) the other two hot wires can hook to any other hot wire. The neutral goes to the white or green and posts to the panel. If the welder has a switching power supply then you must have a three phase converter.
Of the two leads on the LED, one is shorter than the other. The short one is grounded. (Negative)
2 wires to the "R" and "W" terminals on the furnace. Usually the thermostat has similar terminals. If you have air conditioning, then there are 5 terminals to contend with. Look for a wiring diagram on the internet.
The "hot" wire and the neutral wire both carry current (the same amount, in fact) when a load is connected to complete the circuit. The ground wire never carries current except when a fault-to-ground situation occurs. Yes, neutral and ground wires should both be at ground potential, but NO they should not be connected at the outlet.
The leads will placed on your head, or skull.
You should hook up the wires for a tach on a 1985 Chevrolet s10 blazer to the negative side of the coil. You should be sure to identify the positive and negative sides of the coil.Ê
Usually the length of the oem wires from the distributor can give you a general idea. Hope this helps
Need to know what wires and which harness you speak of.
They all should be attached to a wiring harness un less your install a radio then not all wires will be attached to the after market harness in most cases the wires that are not attached can be used to hook up subwoofers
CLIP THE LEADS BACK ON TO EACH METAL TAB
on factory wire harnes, there are 5 speaker wires. 4 are (+). on speakers, but only one (-). when i hook up aftermarket head unit do i hook up all negative speaker wires together
Wire cluster under dash by driver's foot. Installation kit should include a wire chart indicating what color wires are to be used
It depends entirely on what the wires are connected to - this question is unanswerable.
as long as you know what wire does what
Tie the wires on the new plug into the existing brake and turn signal wires.
You should go to your local car shop their prices might be high be a risk taker.
