Yep, you'll have to watch it.
Are there any specific circuits that you think may be on the dodgy side?
I've fried the wiring in my steering column fixing my horn too! Stoooopid me
bypassed the relay doing some fault finding, whilst I gaffa taped the horn switch on!!...there was plenty of current flowing despite the horn not working and after a few minutes, HOLY COW, my steering column is billowing smoke! Now I have a poxy switch zip-tied to my horn button to remind me every day!
You have a fuse box that most "dash" circuits will be flowing thru. You'll almost always blow the fuse first if you have a big short circuit.
Trying to find the short can take a few minutes or go into weeks!! Sometimes they're a needle in a hey stack. In the meantime you can pull the fuse.
Big ticket items.....
Always ensure you have fuses on all your accessories.
Never ditch a relay and have big current flowing in small wiring.
Get a $10 multimeter, they're a must for working with gremlin electrons.
If you decide to start it up, just keep a real keen eye and nose out for smells and smoke. Just turn your ignition to "on" for a few minutes without starting the car and see how it goes.
