Battery Disconnect
Has anyone installed a battery disconnect in a early C4. My 87 keeps
draining the battery because of the aftermarket alarm system on it, if
I don't run it every 2 weeks. I just purchased one from advance auto
and there seems to be very little room to install. Also should these be
used on the NEG side as there is tad more room than the POS. side with
all the wires going to it.

I have one on each of my Corvettes. I like them since I don't drive them much. Only problem is it clears the ECM's memory everytime I unscrew the ****. Both of mine use to run the battery down in a matter of days and since I installed these I have not had to charge m battery and they start everytime. All you need is a 14mm wrench, 8mm wrench, and THIS on the negitive cable.

Or you could just FIX the problem. One solution is to not use the battery draining aftermarket alarm system. You could turn it off or disconnect it. It isn't as though you would be giving up any protection as opposed to the battery disconnect switch.

RRT & others,
Just a word of warning, that exact piece is what kept me from firing my engine for the semi's of the last Pro 10.0 at Etown! Over time that bolt thread on the end of the **** corrodes and will eventually isolate the battery from the frame ground. I've since cabled the neg. terminal to the Moroso style switch without the quick disconnect, problem solved.
PS-don't use the low amperage switch because over time it burns out the contacts, go for the big one.

You can get one at Harbor Freight http://www.harborfreight.com/cpi/cta...emnumber=42292 The local HF store currently is running a sale at $4.95. I have them on my 02 and 87 during the winter.
But I would certainly look at why the drain is so high. A fully charged battery in good condition that discharges to the point where the car won't start after only two weeks is not going to last long.
How old is the battery? I would have a reputable shop perform a charge followed by a load test to see what shape the battery is in.
An alarm system should not draw a battery down to where the car won't start after sitting a couple of weeks. My 02 has far more current drain from the systems on the car compared to my 87. Either car will start easily after sitting for a month without having the float charger hooked up.

I bought the 87 2 years ago and I think the owner had bought the
battery the year before. A no name battery, so I sure its about at
the end. I don't see buying a new battery now and having it set for
4 1/2 months over the winter so the battery disconnect an a float
charger should enough to start it once a month while in storage.
