Dual Optimas & Isolator Installed!!!

[badge49]

I noticed on your first picture you did not sandwich the terminal connectors between two nuts (jam nut configuration). I just installed the same type of isolator and the instructions stated you would not get a good connection without jam nuts and lock washers, and you could also damage the isolator. I like the rest though.

Oh, and I used 4 gauge wire to avoid overheating the wiring and the isolator. Got it at Home Depot for less than $1.50 per foot. Instructions recommended a minimum of 6 gauge for the 120 watt isolators.

Oh, one more thing....If you built your own air intake and it doesn't have a CARB number on it, your truck won't pass smog and you could get a $350.00 ticket if you are stopped and asked to open your hood.

Thanks for the pointers, I hadn't thought of the jam nut thing. I'll probably change that sometime this week and maybe look at upgrading the wires. Good news so far, everything works great and I ran a 6 amp AC drill for a couple hours the other day while helping a friend install fog lights.:navajo:

I did the same thing and thought it did not look right having the terminal right on top of the resin, then looked at the instructions....:

Lol, now that I think of it it really makes sense. Besides having less wiggle room, you get a larger contact surface. Guess I'll be hitting the hardware store tomorrow!:navajo:

Just for reference, the larger nuts are a size 8, and the smaller for the "E" terminal is a 6, metric. I used stainless nuts and lock washers.

Thanks, I was just getting ready to head out and pick some up

Stainless steel isn't very electrically conductive.

yup, copper washers are the best, and not much more expensive.

I know, too hard......but they don't rust and I was afraid of stripping out the copper nuts because I have a habit of overtightning everything.
