Could this be draining the battery?

[OneLethal87GN]

I took the car up the road to get gas and did a few full throttle passes to see where the boost was at. When I pulled back into my neighborhood I noticed the engine temp getting a bit hot. When I popped the hood, with the car still running, I saw the connector on the back of the radiator fan smoking. The shroud around the fan had warped somehow and wasn't allowing the fan to spin. This connector is now cracked and needs replacing. I've been having a problem with a drain on my battery. What is this connector on the fan and could it be the cause? How much is it to replace this connector? I'm not worried about the fan and shroud since I just ordered the dual fan special from Ramchargers. Does the adaptor that comes with the dual fans replace this connector? I want to get the car on the road a.s.a.p. because my boost was only at 12 psi.

That shouldn't cause a drain on the battery. It is relay controlled. The only time it could cause a drain is if the relay was engaged...which could be...they are notorious for going bad a sticking on.

I'd be more worried about what melted the shroud and connector...check your grounds.

After a little investigating I believe I know what happened. I tie-strapped my new 4" maf pipe to the a/c lines running around the fan shroud. I did this to keep the pipe from hitting the alternator. While doing my test runs the engine torqued over and bent the a/c lines forward causing them to press down on the fan shroud. This caused the fan to get stuck and wasn't able to turn. I guess the connection overheated trying to get the fan to spin. What I don't understand is how the engine can move that freely with brand new engine mounts. I had the tie-down kit on my car before the engine rebuild. The hicks that put the engine back in didn't know what it was for and left it in the trunk. I can't seem to find the eye bolt for it so I'll pick one of those up tomorrow. Does anyone know exactly what that connector behind the fan is called? It is right on the back of the fan and has wires running from the fan to a plug in behind the driver's side headlight. Does the dual fan kit from Ramchargers have this already attached to their fans? Man, if the engine torqued over this much with just 12 psi I can't wait to turn it up to 20-25 psi.

sticky relay???

If the relay is sticking will the fan keep running when the car is off?? im having a similar type problem...

If the fan doesn't turn freely, and the car runs hot, the delay relay will energize the high speed circuit when the car is turned off. Then, you'll run the battery power down rapidly.
The delay relay times out once the coolant temperature exceeds a pre-determined point, well over the normal coolant temperature. The idea is to run the high speed fan for several minutes after the car is shut down, to cool whatever coolant is in the radiator. Problem is, the delay relay is not very reliable and sometimes causes the fan to run too long. Or, causes the fan to run indiscriminately if the battery voltage drops too low.

My advice: Get rid of the delay relay. That's right, just remove it from the car. You really don't need it since it's more trouble than it's worth.

i have a 10 gauge run from the alternator, to an in line fuse to a relay. i got home the other night with an overheating car. the 30 amp fuse in the inline fuse is melted beyond recognition and the fuse holder was the same way..... put a new fuse holder in and a new fuse and the next morning my battery is pretty dead. this morning the fuse in that same fuse holder is blown. i dont see any shorts anywhere and i double checked everything....i just moved away to college so i dont have a voltage meter or anything with me. my fan never ever runs after the car is shut off. could this be a bad relay or what? thanks

as far as im aware that is a normal function of the relay (any one know for sure) , it stays on on my car and it usually runs for about ten minutes , if you dont want it to engage just unplug the connectors on the last relay on the right fender (its the big one)
i leave mine off , if you are doing back to back runs at the track plug em in and it will cool the radiator down while you sit

my fan never runs when the car is off. the relay in the back is unplugged. the fuse continues to blow.......
