Questions & Answers

Can someone show me how to connect this to a radiator fan and turn it on and off with a toggle switch? Thank you in advance for any assistance you may provide. ?

Connect one of the large posts on the relay to a large gauge wire that runs directly from the battery or alternator. The radiator fan should be connected to the other large post. Then connect a small gauge wire from your fuse block to one of the small posts on the relay (usually on a circuit that is turned on and off with the ignition switch). Then, using the other small post as a hook, secure it to the ground.

What is this relay's coil resistance?

I have no idea. I'm not sure how I'll be able to quantify it.

Is it true that these devices are waterproof?

Not sure, it appears to be well sealed, but all of the lugs are exposed, so I'm not sure how it would hold up if submerged, or if it would even short out something if not itself.

For my needs, it is more than adequate
5/5

The isolator is used to separate and charge my auxiliary battery, which powers a portable refrigerator. When my auxiliary battery is discharged, my alternator recharges it by passing up to 15 amps through the isolator to the battery. I used 8-gauge wire that was fused with a 40-amp fuse. It was a lot less difficult to set up than I had anticipated. I installed the isolator by drilling two small holes in the firewall. One power wire was run through the firewall to the interior of the car, and the other was run to the engine compartment battery. I completed the turn-around. with a fuse tap connected to the fuse box I connected the isolator and the battery to the same ground point. The installation of the isolator at my local audio shop cost $300. That instilled in me the desire to learn how to do it myself. If the isolator meets my requirements for this vehicle, I will be completely satisfied and will install another in my next vehicle.

It's ideal for use beneath the hood
5/5

On a 1975 Trans AM, I use it as a fan relay. It performs admirably and has never let me down in the scorching heat of Houston. When activated, it hits hard, and when not in use for a long time, it stays closed. Activated by a grounding temperature switch, it's mounted under the hood and exposed to a lot of heat, but it's never had any problems. I'd buy it again, and I'd recommend it to anyone who needs a lot of power for a long time.

This is ideal for converting a high-amperage electric fan
5/5

This is what I used for my 2004 Astro van's electric fan conversion. A high-amperage fan from a Crown Victoria police interceptor was used. The fan stands 19 inches tall and consumes a significant amount of electricity. The van's voltage drops from 13 to 12 when it is running. 5 to 12. There isn't a slouchy fan in sight. There was a standard 30 amp box relay (KC lights branded) in place prior to using the pac isolator. After about a month, the relay began to stick open, causing the fan to drain the battery. Is this isolator overkill? This was caused by the relay housing deforming over time. br>br>Is this isolator overkill? Perhaps. Not likely. I'm sure the Titanic wished it was too much. br>br>A video of it can be found here.

This solenoid is in excellent condition and is ready to use
5/5

This solenoid was purchased for my 1992 Chevy S10's electric fan conversion. The electric fan/motor came from a 1993 Chevy Beretta GT, and the wiring indicated that it required a 30-amp circuit. amp fuse. I figured that since this solenoid is rated at 80 amps continuous and 150 amps maximum, it would suffice. I connected one of the small terminals to the ignition switch on the fuse block and the other to ground to install the solenoid. Of course, I connected one of the large terminals to the hot wire coming off the alternator and the other to the fan's positive terminal. I've put over a thousand miles on this solenoid and it hasn't even warmed up (despite being in the engine bay next to the battery). Overall, if you're doing an e-bike, this solenoid appears to be pretty bulletproof. I'm a huge fan conversion, and I couldn't be more pleased with my purchase!.

Fuse box was plugged in and power was turned on
5/5

This relay was used to power an accessory fuse panel on my Honda Talon by triggering it with the key. It's quite effective.

A month had passed since the last time I saw her. The quality is poor. I would not recommend this product.

Free of flaws
5/5

This was installed in a minivan belonging to a friend (using 8 ga. 4 deep-cycle batteries (recharged with automotive wire) A 110 volt inverter was powered by two deep cycle batteries (connected in parallel) in the back of his van. It functions admirably. It's wired to the ignition (not accessory) side of the ignition switch, so it only works when the engine is running, isolating the battery under the hood when the ignition is turned off. When compared to a battery isolator setup, it saves a lot of money.

It's inexpensive and it works well
5/5

Is it possible to make something as simple as possible? Connect your two positive battery terminals to this relay's large lugs, then connect the small lugs to a switched power and a ground. I used it to replace the battery in my boat's stereo/fish finder. It works perfectly, and I no longer have to be concerned about draining my starting battery while floating on the lake listening to music.
