As I have been in the process of getting my 1934 truck (35 chevy 207 engine) to start, I notice that the engine cranks fairly slow. I have never worked on a 6V set up and figured it was the norm. I tried to start the engine once again today after rebuilding the fuel pump and I could tell it wanted to fire, but it seemed that the starter wasn't turning the engine fast enough to fire. I recently charged the battery after using it while checking several components on the engine the past few months. I removed the starter and I will have it tested along with an extra one I have laying around.
Does this make sense to anyone or am I missing something?
Check ALL electrical connections from the battery back to the battery. A bad connection will cause slow cranking immitating flat battery/weak starter. Tony
1: CLEAN connections on both ends of both battery cables. This means rust and grime. Shiny metal is required. 2: 0 or 1 gauge battery cables minimum (the smaller the number, the larger the wire). Six volts draws twice the amperage as 12 volts. DO NOT use off the shelf battery cables from your local parts store (12 volt cables are usually 6 gauge). You can often find heavy gauge cables at farm stores but always check the gauge. A welding supply store can make cables for you, any length, any gauge. They will need to know the size and type ends you want. 3: Fully charged battery that load tests good. If those three items are checked good and it still cranks slow you have other issues.

Ah damn, really? I cleaned all connections and have all new wires at the starter and the battery, but I never new about being having to use certain gauge. Having said this, are you saying that it most likely is not the starter? I planned on taking both to test and most likely rebuild one, but I would rather save the time driving it up to Fresno as well as saving $150 to rebuild.
It's a whole lot cheaper to put the correct cables on it (which it needs anyway) than to rebuild a starter. If the cables & clean connections don't fix the issue you can look at the battery and starter.

use a set of jumper cables. connect battery neg to starter casing/ground then battery positive positive to positive terminal on starter.
have a friend hit the starter while you hold the cable, so if something goes array you can disconnect quickly !! see if it torques any harder.
I have tested a few on the bench this way, but you have to clamp them securely in a vise as they are torque monsters and will snatch themselves around !!
just think of it like this: wire = water hose smaller diameter hose less flow through it larger diameter hose more flow

I finally got to replacing the battery cable with a 00 gauge and decided to have the starter rebuilt since I felt it needed it. Today I decided to try to start her after many decades of sitting and she started up in just a few seconds.
Best part is I showed the video to the 82 year old man that sold me the 2 rigs and he wants me to take him out tomorrow to see the one run. I hope I can get the one road worthy in the next year or two, so I can take him on ride on the farm.
been working great for years
