Bad MSD Plug Caps?

[SkiDaddy]

Today I had the second MSD plug cap fail in 2 months,:bs2: both have had the metal insert that goes from the wire to the plug break midway where it's thinnest. I'm assuming it's from vibration (I run Wamilton's motor mounts) and the pounding of surf riding (even though it was waist high at best today).:banghead: Both were attached by JSS when he put new plug wires on.

Both times I've noticed the ski was running a little rough, and upon removal there's carbon buildup in the area of breakage. I do run the MSD cap retainers, and the wires run through the OEM rubber "holder" which is attached to the rear head water hose, so they're definately not just flopping around.

Is this normal for MSD caps?

Who makes the best cap for salt water use?

Just stick with MSD, but di-electric greese is your friend. oem motor mounts are the best

Yep.... that happens after you pull them off a few times if you're not real careful.

X2 on the di-electric grease and the retainers help to keep them in place.

You can purchase the connectors without the boots and they also sell a nice crimping tool to install them on the wires.

whoa whoa whoa, crimping tool???? :banghead: :banghead:

where from?:bs2:

ngk screw on plug caps .cut the wire back,screw them on and then superglue them to the wire.they will easily last a few years like that:biggthumpup:

 

[SkiDaddy]

That's what I was thinking Butti, OEM style will probably last muuuch longer.

$75 for the MSD crimping tool. I bit the bullet a long time ago but it works great.

Do you know if the crimping tool uses the same dies as RJ-45/network crimpers?

 

[Fathom]

I'm pretty sure it doesn't.

ouch, def worth it though i bet:smile:

 

[Fathom]

One has to install a lot of terminals to recoup the cost but it's just one of those things you have to suck up, like any other special tool.

If you have an AMP brand crimping tool you can just purchase the dies separate.

The MSD / AMP tool cost around 70 bucks for the good one and the dies are around 30 bucks.

This is the tool I have:

Paladin 1300 series crimper


Seems the RJ11/RJ12 AMP die works with this crimper.

MSD also has a crimper you use in your vice it’s a lot cheaper than the hand crimper. After you crimp solder the wire to the end.

[michael950]

I do not yet have a vice. :shrug:

$50 vice vs $30 die.

A vise is a garage staple what is wrong with you? :cat37:

I'm using a shelving unit as a bench. Need more space for a better bench. My vice is going to cost me $1500 (to buy a shed).

I make due with what I have. Until I am able to get rid of some crap, I have to wait on my vice. It is on the list along with a bench grinder.

You don't need a special wire crimper. I've used the same Klein #1005 for 20 years and if you manipulate the jaws it works great. HomeDepot sells them.

Typically you are supposed to fold back the stripped bare wire end and it gets crimped along with the rubber insulator. I always felt this made a poor connection. What I do when using the MSD boot ends is feed the core wire into the side (see picture) then with Klein I crimp it using the non-insulated crimp (looks like a tooth). This sucker makes for a 0-ohms connection that is resilient to vibration.

If you are breaking the metal tab in the middle you either are over crimping the mid section or have insane vibration. My SJ also rocks like it has a .600 lift cam with 106 degree centerlobes (that is why I have my holders zip tied) and haven't had a problem yet like yours. However I use the boot holders with big zip tie.

 

[SkiDaddy]

No insane vibration, but I did ride a few times w/the wires not firmly controlled & finally noticed when flushing they were shaking like a bass guitar....

i just did a set of these boots last night........I think they are great, until they fail..thats why you keep a set of the stockers in the beachbox so when you have to cut them back its no sweat...
