Hi everyone,
So let me start off by saying that my ADHD and OCD cause me to want to know so I learn new skills often. Let me break down the basics of how I got to this point, 3 motors later, thanks to the mechanic and his slack lazy staff who don't take pride in their work, I ended up with an overheating car, thrice. To cut a very long story short, since then I had to drive with the aircon on in order for the fan to engage, that was fine as we going into summer here in SA. Then after one of the aircon pipes broke, a colleague unplugged the ac condenser to stop it sucking dust in as we were shooting on a farm for a few weeks, I was the snake wrangler on set and the dusty roads were a recipe for disaster. But unplugging it resulted in the fan not working at all and when it was plugged back in, it did not want to come on again, hence the connecting up directly until I could take the time to troubleshoot.
So after testing a few relays in the fuse box and having no luck finding the issue, I had to go to the next step, as the fan was not getting triggered by ECU and the fuse box wasn't giving the fan a power source. So I have removed the fuse box and have been testing the components to see if there was anything.
So the following relays are present :
3 x Nikko YHT KRTB1-225L 12vVDC (Horn, AC & Park)
3 x Fujitsu 53ND12-Y-05 1037F B8 ( Fan Lo , HDLP Lo & Hi)
I desoldered the Fan Lo, Horn & AC to test out of the circuit and they all repeatedly triggered when given 12vdc, my horn was working before so swapped it out with an AC relay just in case, these were returned to the board.
Then each of the SMD relays have a 102 resistor before powering the relay, with no relay in the circuit the resistors came up ..OL on the screen, but here is the thing I am puzzling with, once relays were in place the 102 gave readings varying from 185.5-202, is this in normal parameters, I'm almost sure I checked them before touching the board and were in the 202-204 region. I have attached some pics.
So I remembered a while back one of my LED emergency lights also had a bunch of 102's and I had purchased replacements from a spares place and they didn't have 102's, so he gave me 103's as a replacement to use, my question is can these be used in place of the 102's safely for the car considering its not an emergency light, because I need to get my car back on the road asap? Look forward to hearing your advice.
Thank youy
