Quote from: Carolyn on November 20, 2022, 20:57Yes, do disconnect the battery. The ECU should be fine, but if it worries you, disconnect it.You can use the negative battery lead as an earth.The drill out and bung it ain't a bad call either.Etch primer and paint (both sides0 will be fineYou got this one, John!
Quote from: threepot on November 20, 2022, 22:31Drill it with a stepper bit till its metal. Paint up the edge.Bond in a gromet bung with sikaflex/tiger seal etc.That would be my call every day of the week.It's not structural.... I'm sure if you go poking about you'll find worse elsewhere.
Quote from: jvanzyl on November 20, 2022, 20:42So, I'm going to attempt a very minor patch weld.Couple of questions for those in the know: 1- I'm assuming it's prudent to disconnect the battery and likely the ecu prior, anything wise to disconnect? 2- Grounding.. any suggestions on where or how? 3- is this a stupid thing to do? Should I just enlarge the hole and stick a rubber drain bung in it and can it quits? 4- what do people use to spray onto their welds to stop rust etc? Normal etch primer?

Quote from: Dev on November 21, 2022, 14:56In regards to welding on the car I did a few spot welds when I was making my own exhaust before I brought it over to my bench and noticed that my after market radio and gauges was flickering even though I disconnected the battery. The internet told me that it should not be a problem and it wasn't as the behavior went away but when I seen that happen I knew there is a potential for damaging any one of the modules or tiny circuits. I had to redo the exhaust work later on which required welding on the car so I bought a device that hooks up to the battery that absorbs the surges. I am sure something like this is available in your market. This is just for future reference since it was brought up. https://www.amazon.com/Dent-Fix-DF-601-Surge-Protector/dp/B002XMS0KU/ref=sr_1_4?crid=2BWQ04POPZ9I8&keywords=surge+protector+for+welding+on+cars&qid=1669042201&sprefix=welding+surge+protector%2Caps%2C61&sr=8-4&ufe=app_do%3Aamzn1.fos.08f69ac3-fd3d-4b88-bca2-8997e41410bb
