SOURCE: Screen split with black bar through center, top of picture shows in bottom

It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck

SOURCE: 1991 olds bravada timing question

I have a 1996 Olds Bravada with a 4.3L Vortec 6. The two grooved notches on the harmonic balancer are not used in timing as far as I can tell. Look for a small peg on the back of the harmonic balancer, and once found, you will be able to see it and line it up with the "v" marks on the timing cover. Keep in mind this is on the 1996, but I thought it might be the same since I had a similar problem of trying to figure out which marks to use until I found the peg. You should be able to feel it also.

Here's my suggestion. Take it to the jewelry dept at Walmart. Do you have one where you live.
They'll replace for free - Battery $8
Watch how they do it with their tools and you'll know how to do it yourself in the future.
Good luck

Where can i obtain a wiring diagram

A one phase 3 wire system has a center tap. Two hots and a neutral. Typical 120/240 volts.
A three phase 4 wire system has Three hots in a Y or Delta. The Y system has three hots and the neutral comes from the center of the Y, this is the neutral and grounded conductor, 120 volts from hot to ground and 208 volts hot to hot. In a 3 phase system the voltage is not doubled hot to hot as in a single phase system because the hots are 120 degrees phased from each other and the square root of 3 is the factor, multiply the 120 volts by 1.73 to get 208 volts hot to hot. Multiply 208 by the reciprocal of 1.73 and get 120 volts. Your exact application is not given so it is not known. A delta system is a triangle and the angle of each triangle is a hot wire, one angle would be grounded or the center tap of one of the sides of the triangle. Y is the configuration of the windings of the alternator or transformer and Delta is the configuration as a triangle of the windings of the alternator or transformer where the power supply is.

With a three phase home service, you can only connect two hots from your single phase generator, and the neutral. One of the house's hot does not get connected and any three phase loads in the house should be switched off and kept from energyzing or a circuit breaker or fuse serving that 3 phase load may trip.
Only one power supply can be connected at a time. The power company power must not be connected at all while using an alternate power supply unless your power supply has means to synchronize the alternating cycle.

It is adviced that the loads be kept within 10% of their rated voltage, especially motors.

I need to know what impeller goes with a Q3072 .75hP motor.

The impeller is matched to the pump "wet end". That's the part of the pump that is not the motor. A given motor will mount with several pump housings from different manufacturers. You need to identify the MFR and model of the pump.
I noticed that you have a three phase motor. These are pretty rare in residential installations. Be absolutely sure your system is wired for three phase.

1998 Ford F150 supercab - passenger side door won't open

Get inside the backseat remove two screws that hold the side window. Gently pull the top plastic panel out all around and the panel will come out. It is held by about six clips. Then remove the screws and a nut off the bottom panel. These are all at the top of the bottom panel. Remove a couple of screws thatholds the inside doorl latch. Once all out then simply lift up on the bottom panel and it will come out. Remove the plastic sheet that overs the side door underneath the panel. Now you can see the whole mechanisim for the unlatch. On my truck the problem was with the top cable going into the latch mechanisim. The top cable came loose, out of the slot that held it in place. I pit it back into the slot and made a metal clip to keep it in place. If your interested I can add picture of the clip. Reassembled the door and was done in about three hours.

Wiring diagram for three phase power with two 200 amp service boxes inside building

This work requires a license (or qualified person) everywhere that the National Electrical Code is enforced.

If you're asking how to wire a single phase 200 amp panel from a larger, 3 phase panel of the same voltage - ONE way is to install a 2 pole - 200 amp breaker into the 3 phase panel. Provide 4 correctly sized conductors with the correct insulation in a cable or conduit between the 3 phase panel and the 200 amp single phase panel. Two of these conductors should be black and red (for 120/208 volt system) and connect to the 2 pole - 200 amp circuit breaker terminals, the third should be white and connected to the neutral bus bar. The forth should be green and is connected to the neutral bus bar as well but *only if* it is "service equipment" If it is a "main or sub panel", the green wire should be connected to the ground bus bar. The other end of the conductors should be terminated in a "main lug only" 200 amp panel. The back and red connect to "line 1" and "line 2" bus lugs, the white to the neutral bus bar that is NOT electrically connected to the panel enclosure (do not install the screw or strap between the bar and enclosure). The green must be connected by installing a separate bar that is securely fastened both mechanically and electrically to the enclosure for ground connections.

There is a great deal going on here - and plenty of variables that can change how to do this work, safely and correctly. This is an example of just ONE of many different ways to do the work for a particular installation. There is no one way that works for all situations. If your situation does not support this method - you will have an unsafe installation and subject the building and people in it to a dangerous fire / safety hazard.

Please, consult a licensed electrician before attempting this work.

The string on my grasshog xp gh1000 4, feeds out within 5 mins. What am I doing wrong when I add new string?

Hello, W/D here.

Read all the way through this, with the spool in your hand, before you re-wind the spools. It will make much more sense!

Pull the spool off of the trimmer.
Look on the bottom of the spool. The decimal numbers next to the notches on the edge is your line size (e g. .080). If there are 4 notches, there will be different decimal numbers, indicating that your trimmer can take different line sizes.
Also on the bottom will be arrows, indicating the direction that you will need to wind the line.
Looking at the spool, you'll notice that it is actually 2 spools, and the divider between them has a slot in it. (This will be important in a minute). The section of the spool closest to the bump head is the outer spool, and the spool closest to the machine, with the flat side, is the inner spool.
Insert the proper sized line into the hole in the inner spool core about 1/8", and wind in the direction indicated by the arrows, until the line is just about even with the divider between the two spools, then place the line in the notch that is 180 degrees (on the other side of the spool) from the slot in the divider. When the line is in the notch securely, leave about a 6" tail beyond that, and snip the line.
Wind the outer spool in the same manner, but this time, the line will go into the slot in the divider, then into the notch, and also get a 6" tail.
Feed the tails into the grommets in the trimmer head, square them up, notches to grommets, and snap the spool in.
Push the spool in like you were bumping it to the ground (this frees up the advance for the spool).
Grab the two tails, and give a tug. The line will pull out of the notches and advance about 1".
It's a good idea to clean out the hole where tha spool fits onto the trimmer from time to time, and also to put some graphite dust in the hole every 8-10 times you re-wind the spools, just to keep the mechanism working freely.

Best regards, --W/D--

This is not 3 phase have two legs of 120 ...the red wire? This leg is not a voltage source therefore that wire is not going to fire up that lug only need 3 wires to make this circuit and a neutral is a redundant leg for this box
