Ryan,
NEVER EVER disconnect the battery with the engine running on a alternator engine. It puts the alternator into full field. if the alternator wasn't screwed up before, chances are high it sure is now!! Disconnecting the battery is an old school back yard hack method that used to be used when we ran generators. If someone told you to do it, run if he makes another testing suggestion. Get the alternator off and into a reputable auto supply (not Autozone) and they can test it.

Ryan,
You didn't mention what problems you are experiencing?? Some other things to check are, the condition of the battery, condition of the cables and their terminals. Hopefully you have a starting battery and not a deep cycle. The deeps really don't like the high amp draw of a starter. They are made for low amp draws over an extended period of time like from a trolling motor. One good check is to see what voltage drop you get from the battery to the starter during cranking. With the starter disconnected, energize the coil in the start relay and Ohm out the contacts. They may be burnt and pitted. I see you are an electronics tech so these tests should come real easy. Get back to us with the results.

Hey Peter thanks for all the help i had another Noob question its time for another oil change i have a 302 pcm rebuilt with maybe 15 hours on it i have a case of AMS Oil Z-ROD® 10W-30 Synthetic Motor Oil do you think that would be safe to run in it here is the oil description also running a Napa oil filter

Z-ROD® 10W-30 Synthetic Motor Oil

AMSOIL Z-ROD Synthetic Motor Oil is specially engineered for classic and high-performance vehicles. A high-zinc formulation to prevent wear on flat-tappet camshafts and other critical engine components, along with a proprietary blend of rust and corrosion inhibitors for added protection during long-term storage.

Amsoil Z Rod is fine for flat appet motors
I've tried it myself and liked it but it is pricey. The 10-30 is probably a little thin for a marine engine. If you like Amsoil I would suggest the Z Rod 20-50.

Low oil pressure. It'll work just fine, but you're in Texas. It's hot. I'm in Fl where it's also hot. On my new rebuild, I was only getting 5-10 PSI at idle when warmed up with the 10W-30. 20W-50 brought the pressure back up where it should be.

Ryan,
I agree with Eddie on both using the oil and going to a heavier weight like the 20-50.

Great looking Tique!

You never said what problems you are actually having with the alternator.

the engine died after disconnecting the battery while running so i figured it was a bad alternator i was told this was a test from a not so good mechanic but it was probably just fine but now id like to take it off and have it checked out so im not stuck in the middle of the lake this summer ill look at the points too i always keep a spare set of points and condenser in the boat they are cheap parts to have on hand

Ok, it all revolves around the "test" this mechanic told you to perform! I thought you had other symptoms and you were having actual charging problems.

Ryan,
Yes, that's the normal shaft gland. Is there something that's concerning you?

Are you going to check the alignment? I highly recommend it.

Ryan: this might sound stupid but never overlook the simplest things. I'd had some charging/starting issues on my 74 and thought it might be something big like a failed alternator. Was out with Morfoot one day and he noticed the belt was a bit loose, which I had failed to notice. Tightened it up and all's well ever since.........

Hey guys, Can I swing the conversation back to the alternator???? I have a 77 tique, and shes tired but she still runs. Thing is, when I first got her I noticed that the battery wasnt charging, so I took the alternator in to have it tested and it was barely working... so instead of fixing it so they sold me a single wire alternator.   I can almost hear what your thinking.. cause after I installed it I was thinking the same thing.. my gauges dont work, and now my wiring harness is just hanging there.   Is there any way I can get my gauges and wiring back to working order without tracking down someone who is selling an original alternator???   I have a nice shiny single wire chrome one for trade!!!

No what I'm thinking is I wonder if it was replaced with a marine alternator or an auto parts store one do you still have the old one? Get it rebuilt

I dont have the old one anymore, the guys told me it was junk. The one I have is actually solid chrome that would go into a show car or something, so I dont think its marine either.

Steve,
Take the fancy chromed alternator back to the store. You told them it was for marine use and they sold you the wrong one. Yes, a one wire can be used with slight mods to the wiring. If you decide to use a one wire, ask for a wiring diagram. Most simply get the one wire hooked up to the main breaker from the battery.

Hmmm. Years ago, first year I had my Tique, I put a "replacement" (i.e. new to me, not new) alternator in. I had the "regular" set up to start, but was told the one wire delco would work. I put it in, worked fine, all gauges worked with no modifications to wiring. I just snipped off the two (?) extra wires at the alternator. That was about 10 seasons ago. Wonder why the simple replacement didn't work for you. I wouldn't mind a chrome alternator (to go with my chrome covers) (and I occasionally ponder chrome pullies (sorry Pete). But since mine is fine and I don't like to spend money that I don't have too, I guess I'll have to pass....well that and the fact that its not "intrinsically" safe. Sounds to me like you have reasonable cause to take it back.

Yup, get the VOM out and report back. Check the 12V going to all of them. They are all daisy chained.
