Will this work?

I'm fairly new to using relays, so before I put too many hours into it, could you tell me if this will work or if there's anything I left out?

Turn the diode on your relay around and you should be good to go!

if its jammed force it - if it breaks in the process it needed to be fixed anyway

IMO you should use seperate relays for the remote turn on lead, the fan, and the neon.

Tell Darwin I sent you.

I've been sick lately, sorry I won't be on much.

Does it really matter that much whether I use a seperate relay for each? I had heard from others that It would work just as well like this.

It will work absolutely fine with just the one relay. Any more is just a waste of money. Just make sure you use a high current relay

What is the current draw of the neon? More money, relays are like $1.00 at wholesale. Also you may or may not induce engine noise into the amplifier from the transformer in the neon's power supply.

Good point about the engine noise. Guess it depends on the quality of the neon kit. Typical neons (streetglow gold) draw about 1/2 an amp. Where can you find relays for $1? (seriously, I've been paying $3 a piece for the bosch relays I use) Also, whoud you happen to know where I could find two coil latched relays?

I'm going to just plan on using one high current relay from radio shack (#275-226) for now, & I'll let you know about the engine noise after I have time to do the install. I'm too busy with work right now. I don't know the current draw of the neons. I know they are streetglow, but they were given to me used, so that's all I can tell you.

ok, this may be a stupid noobie question, but my fan has 3 wires instead of 2 (positive, negative, & ground). Yeah, I'm not so new that I don't know that. Anyway, in my diagram, I had the negative wire going to ground, so what do I do when I have both negative & ground?

are you sure that's a 12vdc fan and not a 110vac?

yeah, it's 12 volt DC. It came out of a computer I had laying around. It has 3 wires: red, yellow, & black. It says the brand is POWMAX.

not too sure about that one....seeing as it's out of a pc and not exaclty made for mobile apps. I'm sure if you hook up just the ground and power it will work...but fuse the power wire to be safe....if i were you i'd just go to radio shack and buy a 12vdc mini-cage fan for like 10 buck....really strong fan and really cheap

your standard pc fan has 3 wires, 12v, ground, and signal, the 3rd wire is what tells the motherboard how fast it is spinning and can just be discarded (CUT OFF!!!!). Plus you can get them for like a buck online.

I found another fan that only has the two wires, so I don't have to worry about it. Thanks for your help. Hopefully I'll actually have time to install this sometime soon.
