Message	I've heard of components burning up sometimes when people "hot-swap" ECUs. By the way it's a diode. Not that it helps much...
Follow Ups	Installing a new EPROM in my ECU and look why I saw :( - Borg79(ON) 12:26:47 03/21/04 Ever swap the ECU out with the battery connected? - SooperZ95 12:42:16 03/21/04 Hmmm - Marshall 12:44:26 03/21/04 but just that one diode??? There are many other diodes - Borg79(ON) 12:50:29 03/21/04 I know it seems unlikely, but... - Marshall 13:40:30 03/21/04 diodes dont break down when hooked up backwards... - halik 12:56:24 03/21/04 They do have a reverse break-down voltage. - SooperZ95 13:03:32 03/21/04 Well i am not having any problems with the ECU, I just - Borg79(ON) 13:10:25 03/21/04 Except diode breakdown is not normally destructive provided - therin (Plum) 13:55:11 03/21/04 The structual damage is a mere result of electrical failure. - SooperZ95 14:15:16 03/21/04 Do you think it will be OK though?? ANOTHER Thing, - Borg79(ON) 15:06:46 03/21/04 Wrong. They do break down. - Marshall 13:26:45 03/21/04 yeah, i'm having a problem at work with powersupplys - Halo Z 13:40:54 03/21/04 that sucks... (n/m) - Marshall 13:47:13 03/21/04 yeah, OE was a 380 volt rating. the crap they got was 23v. - Halo Z 19:47:37 03/21/04 I've never hot swapped the ECU :( (n/m) - Borg79(ON) 12:49:20 03/21/04 Looks like a couple of parts - therin (Plum) 13:33:41 03/21/04 it's a diode (n/m) - Halo Z 13:37:27 03/21/04 Hmm, at second look, I don't know if it's a diode or not. - Marshall 13:50:14 03/21/04 Re: Hmm, at second look, I don't know if it's a diode or not. - therin (Plum) 13:55:48 03/21/04 Trust me dudes, it IS a diode. (n/m) - SooperZ95 13:58:44 03/21/04 Did you read my post?? - therin (Plum) 14:02:08 03/21/04 What is questionable?The ONLY bad part on the PCB is a diode (n/m) - SooperZ95 14:06:01 03/21/04 Uhh so the two melted resisitors in the second picture - Musashi Sword 17:34:51 03/21/04 They aren't resistors, they are the leads of the diode! - SooperZ95 19:22:16 03/21/04 ok i see how it is now those two legs looked like - Musashi Sword 20:29:38 03/21/04 I think that's just the backside of the board. - Marshall 19:23:51 03/21/04 you're right. - Marshall 14:10:48 03/21/04 It is a diode, it says D102 under it not R (n/m) - Borg79(ON) 13:57:20 03/21/04 *shrugs* Ask Ash I supose, hes the ECU guru (n/m) - BooZted (Soon supercharged) 15:01:14 03/21/04 Don't even bother .. get another ECU - PLEAZURE in CA (SD) 15:09:06 03/21/04 Re: Installing a new EPROM in my ECU and look why I saw :( - Cosmik Debris 15:24:19 03/21/04 Way too large soldering iron=household laundry iron? :p (n/m) - NC_Z 19:05:16 03/21/04 Send it to me.. I've fixed that problem many times. (n/m) - AshsZ 21:16:56 03/21/04
