Reddit reviews Mastech MS8268 Digital AC/DC Auto/Manual Range Digital Multimeter Meter

You should certainly have your typical "manual" screwdrivers....but I would recommend a rechargeable electric driver 100000x.
The time and effort it saves is incredible. You can get a fancier one, but this one has served me well for years.

Regarding the outlet tester...get it if it makes you feel better...but, really, what good will it do? Do you know how to fix a bad ground? You could do the same tests (plus a lot more) with a good multimeter.

A multimeter costs like $20 FYI, and is a good tool to have.

The Pioneer will fit your car, and think it's a good choice.

A soldering iron, digital multimeter, shrink tubing and good electrical tape (3m super 33+) are all good investments to have if you are doing car audio/electrical work.

If you don't have access to a soldering iron or butt connectors you can use a military splice and electrical tape. If you do solder the connecting you can still do a military splice first.

For a decently priced digital multimeter I'd recommend this one.

My job uses Fluke, but they are pretty pricey. If you are only going to use them for Ecigs, then like everyone else has said the 20$ digital multimeters are good. Sears, RadioShack, Home Depot, and Lowes all carry budget priced tools.

I bought this one for my personal use, but I use it for PC and Auto troubleshooting as well.

Just got one of these:

It's been great so far.

I've never used a fluke before, only heard good things about them. I will say that the one I recently purchased http://www.amazon.com/gp/aw/d/B0050LVFS0 is worlds better than my previous cheap ones.

I don't see anything particularly wrong with that -- any shoddy multimeter will do fine for ohming out a coil.

I'd suggest getting a halfway-decent auto-ranging multimeter just because they're nice to use and because whatever you buy will inevitably get tossed into the toolbox and you'll be using it for other stuff for the house or car.

This one seems okay for an inexpensive meter, based on all of two minutes of searching around: http://www.amazon.com/dp/B0050LVFS0

I am looking at this one - http://www.amazon.com/dp/B0050LVFS0/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=28TFHN6YFDN48&coliid=I2YTJG4QJS5MMA

I wouldn't say that all multimeters are accurate. I have a few of the free harbor freight ones and I wouldn't trust them to read ohms. I only use them to test voltage of my batteries. You're supposed to test the resistance of your leads and then subtract that from your reading that you get, but I still find that it tends to be .1 or .2 above or below my real ohms.

I know this is one that a lot of vapers use. I heard its pretty accurate but I can't comment on that myself as I haven't owned one. It's an auto ranging one so you don't have to include the resistance of your leads if you're trying to read ohms.

If you're going for accuracy, I would trust my life with a fluke multimeter but obviously that's quite far from being affordable. It would be worth picking one up if you could get one for cheap from someone you know or craigslist or something though.

I think it's more to do with the battery not having enough time to fully charge due to the short driving distance.

Perhaps you should pick up a voltmeter for like $10ish on Amazon.com or a local shop? You can take measurements in the morning when it's not starting well and later in the day when it is starting well. It'll be difficult for the dealership to replicate your driving pattern so perhaps it's best that you do it.

Something like this: http://www.amazon.com/INNOVA-3721-Battery-Charging-Monitor/dp/B000EVWDU0/ref=sr_1_3?ie=UTF8&qid=1406872499&sr=8-3&keywords=voltmeter+car

I have this one but it's a bit more complicated and works on other things also: http://www.amazon.com/Mastech-MS8268-Digital-Manual-Multimeter/dp/B0050LVFS0/ref=sr_1_7?ie=UTF8&qid=1406872598&sr=8-7&keywords=voltmeter

Popular Science liked it 4 years ago. I keep a similar one in the glovebox of my car, but for the same price you can get a better meter like the one I linked before. My Fluke 87 was only $25 a few years ago on fleabay with blown current fuses, although I took a chance on it possibly being something more than the fuses. Couple that with with some $5 agilent probes also from fleabay and it was a lot of bang for the buck.
