got it running!

I got it running! I need to adjust the throttle linkage better and the test out the temp gauge but other than that it seem good!
I also need to install a second battery,,

Re: got it running!

why do you need a second battery?

Re: got it running!

Hello Tom, when cranking is loosing too much voltage.. I had a post in the electrical section that explains it better..

Re: got it running!

Sounds good. What 4150 adapter did you use on that Team G? I have one but all I have is the 2" adapter and it's kinda tall.

Re: got it running!

I would get better battery cables seems there is too much drain when cranking, since that is the case your gonna always be chasing a electrical problem, what type of wire and what size is feeding the starter? what is the ground wire size and type? you have a very high draw in the system. is the fuel pump electric? is it running when your cranking the engine?

Check wire resistance and run a ground to the battery.
I had this problem myself once.
Option is to run the ignition box only from a small battery so it see only 13volts and no starter drain. Good luck

Re: got it running!

Hey guys, I actually didn't use a adapter; the carb and manifold both use the 4150 series flange. ( I need to change my stats )

I am using the thickest welding cable I could buy as a cabling, all the way to the starter

https://www.princessauto.com/en/deta...t-/A-p8228041e

I have 3 grounds with the same cables size attached to the frame..2 from the engine and 1 to the frame..

-I would like to try a ground from the negative post of the battery to the starter at some point and see if it makes a difference.
-Perhaps 90 amp Ford style solenoid might be giving me some problems or the 150 amp cut off switch? I don't know if the lower amperage rating on these items might give me a voltage drop?

To start the engine I turn on the pump to fill the bowls and then turn it off..I then turn over the starter and hit the IGN..

I went to a battery store last night and learned a lot. If I wasn't looking into short term solutions I would get a Northstar AGM battery, they initially give a lot of cold cranking for a few seconds and then steady down to a lower level. This engine was using a Optima red top battery to start it before that uses the AGM technology. My 78DT we cell battery is probably damaged due to being worked below 10 volts..

A separate battery for the IGN system might be a good option as well, for now I will try the 2 battery method..

Re: got it running!

I would try using larger battery cables before going to a 2nd battery. My $0.02 is that the second battery is just masking a voltage/amp drop problem.

Re: got it running!

If I have some time this Easter weekend; I will use booster cables to ground the battery right to the starter..that might show some problems.
I have to adjust throttle linkage (pedal needs more travel), install another temp gauge, etc

Re: got it running!

Glad my Power Pack helped you start it .

In the 80s my Winter Car had two Batteries as the 318 ci Dodge Monaco would not turn over fast enough with just one

But the good part was the bugger never got stuck in a Snow Storm,
it would plough through anything since she weighed so much

He is correct! Welding cable is not good for 12volt as it has too much resistance, you really need to look at the link above I quoted and see the difference, 12 volt battery specific cable looses less amps and voltage over distance then welding cable, many a racer has chased voltage drop due to using welding cable instead of proper 12volt cables. Just FWIW.

#4 is too small. Go to 2/0 and use proper battery cable. Most big truck shops will have rolls of Grote brand 2/0, and the crimper tool. Use the good heavy cable ends with the proper size 5/16” stud hole. Not 3/8”.
See what they would charge you to make some up.

I went from #4 to 1/0 and there is a huge difference in the voltage they carry.

Be sure the block is clean where the starter mounts. No paint. Battery grounded to the engine, then engine to frame from the same place on the engine. Then frame to body.
Your voltage issues will be gone.

Re: got it running!

Jeb, you have it backwards.
Welding cable has more strands per inch for greater current flo vs battery cable. We also use DLO, it's very similar.
I'll take more strands per inch all day.
Double the current carrying capacity for the same size conductor.

Re: got it running!

thanks again Greg!!
I did the negative battery cable to the starter connection and didn't notice any change as compared to no connection...
This was after I just charged the battery but I did notice it turned over much quicker for both scenarios. I had turned over the engine before after a charge before and it didn't turn over this fast??



I also changed the water temp gauge, replaced a faulty relay, put new oil oil, figured out throttle linkage. I still need to change some carb gaskets, the rear accelator pump needs to be changed..
