Connector w Bolt

Torqued everthing under VC really needed it specially the 2 rear on drivers side.
My question is when i looked the the connector w the bolt thru it I noticed what looked like corrosion (whitish coating) on a few of the pins.
Tried spraying w contact cleaner helped some but still not clean.
IS there a better way to clean them. I was afraid to use a wire brush for fear of shorting something out?

If it is off (and it better be if you are under the VC. LOL) you shouldn't short anything out.

If you going to be poking into the connectors i would pull battery connections to be safe... Use a wire brush or some braided wire to scrape a little bit. Contact cleaner then spray on some di electric grease. That should do it.

Thanks, thats what i'll do. Di-electric if I disconnect and DIE electric if I don't.

di electric grease does not conduct electricity so I would not put it on any pins. The main purpose for it it to put around the rubber part of the connector to prevent moisture from getting in. I use to think it conducted electricity but I found out different lol.....

NOW m really confused. Di electric on the outside but what can I put ON the pins and ~pin holes~ to clean and keep from corroding?

I would just use some electrical parts cleaner and call it good. That connection did have some kind of white grease from the factory but not sure what.

Look at this link on the d-electric: http://continuouswave.com/ubb/Forum6/HTML/001202.html

To confuse you more.
I know what folks say and what is written. But I use a little on the pins. Guilty. If it did conduct electricity that would be terrible. It would be one shorted out plug. I have been using CRC for years. Light bulbs to trailer plugs to boat stuff. No more corrosion problems for me. I realize there has been forum chit chat everywhere about this. But live with less contact surface from corrosion that continually gets worse over time or a little less contact that stays fresh for ever. It is indeed a individual judgment call. I have it on my 42pin connector and every other connector i work with. right or wrong.

Dielectric grease can be used on the pins. The pins make electrical contact under pressure through the grease with no problem. If there isn't enough pressure to make contact through the grease it's not going to be a reliable connection anyway. The grease is to prevent moisture from entering the connector. Used in plenty of military applications. Don't ask me how I know. Only down side is a connector that is unplugged part of the time and left open like a trailer plug - the grease collects dirt and dust like a magnet if not capped.

I would not get in the habit of putting it on everything. I would rather use some kind of anti-corrosion spray that was lighter or a ligher grease. The di-electric seems to be pretty thick and can change electrical characteristics of the connection.

Dielectric grease will not effectively change any electrical characteristics of a connector carrying DC or low frequency signals, with one exception, and that is dielectric breakdown, which it increases, and is a plus, not a detriment. If kept clean, it also lowers insertion force and wear on contacts.

So, your saying put it on all contacts? If you put a non conductive material between two conductive materials what do think is going to happen. Higher resistance. Do what you want but don't think you should tell others to go that route. I worked on test equipment and never heard an engineer tell me go put some di-electric grease on it or any other kind. So when di-electric grease breaks down you have better continuity? That's what you stated.........

I'm not saying put it on anything, I'm simply stating how it works. Please carefully reread my post. I did not state "when di-electric grease breaks down you have better continuity'. I stated that it increases dielectric breakdown values. Dielectric breakdown is when the resistance (in the case of a connector) between two adjacent pins is reduced to the point where an arc will occur when under power. The "dielectric" or insulating material deteriorates to the point where it's insulating ability will not insulate the voltage between the pins. That's why it's called dielectric grease. It increases the voltage at which breakdown occurs, thus lessening the chance of an arc. As I stated before the grease does not prevent metal to metal contact of the mating surfaces of the pins, thus you are not putting a non conductive material between the pins. Use it or not ...matters not to me.
