[QUOTE="Chromatic, post: 8222473, member: 659121"] [USER=655960]@bbeljefe[/USER] ; No, thank you! I totally understand it 100% now. I have so many uses for relays now,.. lol. I thank you for imparting this simple information to me,.. I can be dense sometimes. Anyhow -- What was throwing me off was that I drew my diagram wrong! I had terminal 30 going to the Amp (battery) AND to the Fan. I ALSO on my diagram had 87 going to the Fan. That's not right. 30 is going to be my input power.. so that's going to be fused at 3amps from the amp power wire.. and will NOT go to my fan (directly) as terminal 87 will go to my Fan's positive + Remote wire to amp. That makes so much sense.. as the main "power" is sent across 30 to 87 when it switches as the electromagnet in the coil powers up and pulls the switch over connecting the circuit.. I was trying to figure out why (on my diagram) I was putting power from terminal 30 AND 87 to the fans positive.. that wasn't equating with me.. and it should cause it's wrong! Terminal 30 is just giving the relay it's MAIN 12v power.. And 86 (I know 85 and 86 can be siwtched around.. as can others... ) is the "trigger" to power up the coil.. which will then allow terminal 87 to receive the power from the battery (amp.. but it's the battery wire).. Which is going to power the fan,.. and is going to send power to the remote wire to the amp. Soo.. as long as that is right, I'm good on wiring. But,.. let me ask you this -- Now the remote input on the amp is going to get higher than the 250mA the headunit is putting out.. does that matter at all? (Since the remote from HU is now going to go through this relay, and out terminal 87 which will be feeding more power to the remote in than it was getting. On that note.. It should also work if I spliced the HU remote wire and had one end going to the amp, and one into this relay at 86. The 87 JUST going to fan, and not to remote in on amp (as the spliced remote would be going into the amp ). But, you said to run remote to 86,.. and then feed the remote input on amp from 87 -- So it must not make a difference if the Amp's remote in is receiving 250mA or 3 amps. Thank you for your patience, and it was far from condescending.. I'm being very dense on this matter, and I apologize. [/QUOTE]
