I've tried a new tks enrichment module and even tried a new 50 amp. Still acting up. I've ran all the diagnostics in manual 41 for tks. The only thing I'm not seeing is continuity at temp switch when running and disconnected at 130 degrees or so. Maybe it is the switch after all?
The only...
This makes sense. I noticed the module didn't stop hissing like it should and was not warm shortly before the diode went up. I will try and confirm then order. Your help is immensely helpful dodge.
I wasn’t able to reproduce the issue today with meter hooker up
...and to add to the perplexity, the diode started smoking and a hole burnt through it. It was very hot. Never seen that one before. Maybe the temperature switch is revealing it’s true nature? At the time it smoked I took an ambient...
It's a standard 3 fuse. It’s actually a red and purple wire separately spliced into the ignition with the red the only one going to that fuse. The purple runs up to a harness.
So is there ever a scenario where the tks enrichment or sensor would cause an issue with the ignition system? We've checked all wiring in the ignition system (except harness internals) and replaced or tried other parts within the ignition system. It still will lose voltage and turn off...
So I looked at this again with a mechanic. All the suggestions here were explored but it only died once in fifteen minutes. Same thing after cooling off an hour later: died once within warmup at idle. Might be weird but seems like after it warms up 10-15min it is less likely to occur. I drove it...
This could be coincidence but I started messing around with the harness that’s attached to the TKS module and the bundle going elsewhere. I can’t readily reproduce, but it seems like it wanted to drop more consistently after I was messing around with the wiring around that area but it wouldn’t...
so this is that green wire and there’s no busbar anywhere within the range that this could connect to. It’s just at the block with the rest of the grounds. Pretty weird huh?
I can see about doing a temp or measuring resistance. Everything is grounded at block, 5 or so wires. When I replaced the negative battery cable as a test, I did see one random green 10 gauge ground wire attached to block that was not connected to anything else... which is interesting. I...
