Here's a picture of what it should look like in there.

Royal/Excelene makes good welding cable, 600 strand count is for 2ga+ sizes.

The strand count does nothing for the current carrying capacity, but it does make for more flexible cable and can reduce the stress on the connection posts if the cables have a short/sharp radius turn before the post.

You do have a certain amount of Styrofoam like "potting" compound inside the OBC hole.

The actual Hall Effect sensor is located in that little gap on the toroidal blue core, as long as that core did not shift and damaged the sensor, it may work.

Here is an inside view of the OBC.

I flew out of MCAS Cherry Point on the first C-141 that ever landed there.

I included the Parts manual also.

Change Your Thinking

It will take just 37 seconds to read this and change your thinking..

Two men, both seriously ill, occupied the same hospital room.

One man was allowed to sit up in his bed for an hour each afternoon to help drain the fluid from his lungs.

His bed was next to the room's only window.

The other man had to spend all his time flat on his back.

The men talked for hours on end.

They spoke of their wives and families, their homes, their jobs, their involvement in the military service, where they had been on vacation..

Every afternoon, when the man in the bed by the window could sit up, he would pass the time by describing to his roommate all the things he could see outside the window.

The man in the other bed began to live for those one hour periods where his world would be broadened and enlivened by all the activity and color of the world outside.

The window overlooked a park with a lovely lake.

Ducks and swans played on the water while children sailed their model boats. Young lovers walked arm in arm amidst flowers of every color and a fine view of the city skyline could be seen in the distance.

As the man by the window described all this in exquisite details, the man on the other side of the room would close his eyes and imagine this picturesque scene.

One warm afternoon, the man by the window described a parade passing by.

Although the other man could not hear the band - he could see it in his mind's eye as the gentleman by the window portrayed it with descriptive words.

Days, weeks and months passed.

One morning, the day nurse arrived to bring water for their baths only to find the lifeless body of the man by the window, who had died peacefully in his sleep.

She was saddened and called the hospital attendants to take the body away.

As soon as it seemed appropriate, the other man asked if he could be moved next to the window. The nurse was happy to make the switch, and after making sure he was comfortable, she left him alone.


Slowly, painfully, he propped himself up on one elbow to take his first look at the real world outside.
He strained to slowly turn to look out the window besides the bed.


It faced a blank wall.

The man asked the nurse what could have compelled his deceased roommate who had described such wonderful things outside this window.

The nurse responded that the man was blind and could not even see the wall.

She said, 'Perhaps he just wanted to encourage you.'


Epilogue:

There is tremendous happiness in making others happy, despite our own situations.

Shared grief is half the sorrow, but happiness when shared, is doubled.

If you want to feel rich, just count all the things you have that money can't buy.

'Today is a gift, that is why it is called The Present .'

The origin of this letter is unknown, but it brings good luck to everyone who passes it on.

Battery cables

Electrically, all cables have resistance and the thinner the conductor is, the more resistance it has and the more resistance, the more of the amp flow through it is converted to heat, which is power wasted in the amp delivery system rather than being converted to motion by the motor.

A 36V PDS or DCS cart that has been upgraded 48V with a 6 x 8V battery pack has a total of about 20' of high current cables. The following is the resistance for the copper conductors alone.

20' 6Ga = 0.007902Ω
20' 4Ga = 0.004970Ω
20' 2Ga = 0.003126Ω

A few milliohms does appear to be very much until you start pumping 500A though that resistance since W = I^2 x R.

Power loss at 500A for 20' 6Ga = 1975.5W
Power loss at 500A for 20' 4Ga = 1242.5W
Power loss at 500A for 20' 2Ga = 781.5W

Since 746W = 1HP, the cable loss can also be stated as follows:

Horse Power loss at 500A for 20' 6Ga = 2.65HP
Horse Power loss at 500A for 20' 4Ga = 1.67HP
Horse Power loss at 500A for 20' 2Ga = 1.05HP

Of course, your motor will only draw 500A for a brief period of time and will only be drawing someplace between 50A to 100A most of the time, but the loss ratios are the same.

For a 500A controller, go with 2Ga.

FWIW: My first upgrade was 2Ga cables on a otherwise stock 36V PDS that was only three years old at the time and I had a noticeable improvement if low end performance.

i have a set of piston rings I had lying around from 2006 and I have a 99'
Rebuild manual
What I need help on is identifying which piston ring is compression and the wiper

One ring is completely grey and the other one have a silver machines edge on the outside
The completely grey one is perfectly square no beveled edge but the grey/machines edge one has a bevel to it on the inside

Also they have a small dot/ circle so really don't know top from bottom
