Very true boost but again why fix something thats not broken.
As soon as I start the engine, I turn on the fans, they stay on constantly.
True there may be better ways to shroud fans and if we want to turn this into a thread about best practices fine but Rob does not have a problem IMO in the least so WHY do anything different?
WIre it direct to the ignition switch through a relay.Rewire the fans to be parallel if you wish and forget it.No need for anything more unless you just want to do some sheetmetal for practice. IMO ,again,don't fix what's not broken.
Being I am not there seeing this I gotta say a couple things. First. I do agree a good bit with Fabr that it seems to be ok and thus might not need more love.BUT as noted in another thread on this board IF the fans are wired in series like you first mentioned and one of them DOES fail the other will stop. (Unless it shorts directly across the bad fan then the remaining fan will get 12 volts! Which would help it draw more air. I would not count on this!!)Going to parellel as you tried made current an issue it seemed on your charging system. Also noted with lights on and parellel it was having issues. So that might limit night riding. If you do that. They boot us out of the Silver Lake dunes here in Michigan right after dark so you cannot do much night riding. We used to get out earlier to get in line (yah we have a tiny parking lot here and have to get in line to get in if there is any real crowd. It sucks!) But when I first went to Glamis we would go out a lot at night and it was intensly fun! One other thing I noticed that I did not see was you never mentioned what the ambient AIR temps were while you were riding around? (I don't think I missed that?? I even relooked) If it was cooler those days then a few degrees cooler will make a buggy run a good bit cooler. But you get a hot day it might not cool as well. Forget about a good run some night when your friends want to go and its hot. That would be a bummer. (assuming fans wired in parrellel and trying to run the lights. I know you put them back to series. But will series cool enough on hot days/nights??) Plus if your taxing the electrical system and burn it out you might be sitting a good ways from camp. If you do not have someone to tow you out and leave your rail there to walk out I have heard of dipweeds finding brokedown rails at Glamis and stealing them or at least stuff off of them. Not good. Tires are easy to steal and hard to ID on another rail racing by.You might find fans that bolt to the shroud you have just as it is if you simply replace them. But if not and you need to modify it why not do a bit more while at it? You could make the whole system a little better and thats never a bad thing if you tired some simple mods to the shroud as mentioned. Including a separator strip that would isolate the two fans in the middle of the shroud so that you could run only one if needed and take it easy to get back to camp. (A soft strip of seal that goes right to the fins and touches the shroud between the fans) Plus the mentioned ways of allowing the fans to draw air through the whole radiator area. Not just the fan diameter. (Edit: this should have read push air not drawn in this case.) Get lower current draw fans that are set up to be pushers (the blades MADE to be a pusher. That makes a big differance in air flow!). If the place you get parts from says they do not exist then ask for better help or go to another store. As noted it may be fine with just new fans if these are ailing but the little bit of work to make it more reliable would be worth it VS the extra heat. Plus if you ever try to boost motor power then you will need more cooling for sure. Even a day of hill climbing drags as it is now with friends may make it run hot and make you sit and watch and cool down while they play. Its a matter of if that may be ok with you IF it happens to happen. But it would be more fun to have it do what you want. Not the other way around. (Sorry Fabr! ) Its just my thoughts on it.
The fans are definitely being replaced. I will wire the new fans in parallel, just for safety. More charging capacity is my real issue. Who makes a good high output stator? Are they easily replaced?
