Question about IBM LENOVO 24V POWER SUPPLY 42L0085 Power Supply

Adding trailerbrakes to a 24 volt truck

I have a gooseneck that has electric brakes. I have 24 volt truck that has a 12 volt reduced 6 pin round trailer plug that will suit the gooseneck . My question is how do I add the electric brakes from the 24 volt truck to the now reduced 12 volt plug to make the electric brakes work. I have 24 volts from the brake, can I just wire as normal (blue wire to trailer plug) or do I have to reduce the voltage from the brake then add blue wire to the plug?????

Are your electric brakes rated for 12 volt or 24 volt, that is the question. YOu have to supply the voltage at whatever the brakes are rated for.

Tandem batteries... is a fairly loose term to be dealing with on batteries... SIMPLY BECAUSE THEY ARE EXPLOSIVE.

Any can tell what the 6 wires on the ignition loom want to fit turbo timer ?


Use a volt meter. with the ignition off see what pins have 12 volts. turn the ignition on, see what additional pin has 12 volts. turn the ignition switch to accessory, see what additional pin had 12 volts.

Smps not working

Nothing special about that Power Supply except for the PRICE!

It's just a regular ATX SMPS with a 575 Watt maximum rate wattage, and an 8-pin EPS +12 Volt power cable.

The HP part number is HP 405349-001
I just THOUGHT the above model was expensive,

http://www.sears.com/hp-405349-001-hp-575watt-power-supply-for-workstation/p-SP101A9790S5492818201P

Uses one 24-pin ATX main power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

One 8-pin EPS +12 Volt power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#eps8

[NOTE*
NOT to be confused with the 8-pin PCI Express power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#pciexpress8

Yellow wires are 12 Volt wires. Black wires are Ground (Negative) wires.
The 8-pin EPS +12 Volt power cable has FOUR 12 Volt wires.
The 8-pin PCI Express power cable has THREE 12 Volt wires ]

I believe 4 SATA power cables,

http://www.playtool.com/pages/psuconnectors/connectors.html#sata

,and a few 4-pin Peripheral power cables, ('Molex'),

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

Power Supply case dimensions are approximately
6 Inches Wide, 5.5 Inches Long, and 3.5 Inches in Height.
(152.40mm Wide, 139.70 Long, and 88.89mm in Height )

36 Amps combined for the two 12 Volt power rails.
(12V1 = 18 Amps, 12V2 = 18 Amps)

This is an example of a replacement SMPS,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=899124&CatId=1483

I'm running one of these right now in a Dell Optiplex 745
Yes, even though the power cabling noted on the Tigerdirect ad is erroneous, it DOES have an 8-pin EPS +12 Volt power cable.

One 24-pin ATX main power cable
Four 4-pin Peripheral power cables
Six SATA power cables
One Small 4-pin Peripheral power cable. (Used for a Floppy Drive, or a Card Reader)

Two 12 Volt power rails. 12V1 = 23 Amps, 12V2 = 20 Amps
Combined = 43 Amps on the 12 Volt power rail.

Repair?
Due to the possible electrocution hazard, I don't post info on repair.
I will state;
The capacitors need to be PROPERLY discharged, before attempting to work on the unit.
The Radial Aluminum Electrolytic Capacitors are the weakest link.

I am trying to troubleshoot whether or not my ultra x2 connect 550 watt power supply is bad. When you press the power button on the computer, the light flashes and then noth9ing else happens. The light...


Well here is a way to check your power supply, on your hard drive connector using your volt meter and measuring from ground. this would be using one of two middle connectors it should measure +5 VDC on the red wire and + 12 VDC on the yellow wire. If these voltages are good then we got to see if the power supply is producing the -12VDC voltage. This voltage is ussed by the syustemboard on pin 14 of a 24 pin power supply. I would recommend not having your system board plugged in while measuring these votlages, but the power supply may need a load, I would plug in the cdrom.. Below are a couple of picture to explain this and a link to a website that has this documented.

http://www.playtool.com/pages/psuconnectors/connectors.html

dfish26_1.jpg The 24 pin main power connector was added in ATX12V 2.0 to provide extra power needed by PCI Express slots. The older 20 pin main power cable only has one 12 volt line. The new 24 pin connector added one line apiece for ground, 3.3, 5, and 12 volts. The extra pins made the auxiliary power cable unnecessary so most ATX12V 2.x power supplies don't have them. The 24 pin connector is polarized so it can only be plugged in pointing in the correct direction.

I have a 06 town & country with a four pin wiring harness. Our pop-up camper has a 7 pin round plug. I used an adapter to connect them but it caused a blown fuse; was told by shop that would have...


I'm assuming your pop up is big enough to have electric brakes, thus the 7 pin connector. If it doesn't, you can use an adapter (probably like you have) provided the 4 pin was wired correct in first place, but if not, figuring out what's what, shouldn't be difficult. If you do have brakes on the trailer, then the law requires it to be wired such that the brakes are operational. If your thinking of tackling this yourself, and are reasonably familiar with 12 volt wiring, we may be able to help, if not, any hitch installation place, or RV center should be able to give you a reasonable price to wire it properly for you.They usually know what wires to splice into without replacing any harness, as well as have knowledge of proper installation for electric brakes as well. Usually ends up being a choice of a higher labor price, but less time for those experienced in doing that, or paying an inexperienced guy a lower labor rate, but takes him twice as long. personally I'd go with those who do it all the time.

Want to connect electric lights to ez-go electric golf cart. It is a six battery system and I want to simply add a front light and rear red light.


You said you have 6 batteries. Are they 6 volt or 8 volt? Hint-- 6 volt has three holes in the top and an 8 volt has 4 holes on top of the battery. Battery manufacturers recommend the use of a voltage reducer wired to the whole bank. This take the 36 or 48 volts down to 12 volts and is regulated. this is recommended so as not to stress just 2 batteries. If you have 6 volt batteries, you can use any 2 that are wired in series.
