H cutout performance

Well, I went ahead and took my entire wiring system off my H and started fresh. I priced a cutout from NAPA and nearly had a heart attack... $90. ouch! I bought a solid state one from a local gen/starter rebuild shop for about $20. It's rated at 25 amps and says it will work on 6, 12, or 24 v. systems, and as an experiment, I can live w/ $20 vs $90..
Anyway, I also disassembled the switch and checked all the contacts and all seems good. I rewired everthing according to a wiring diagram I got on this forum, and it seems to work fine, except the charge rate isn't what I would call great. The battery is weak right now, and barely turns the motor over. Would a bad cell, or some other battery malady cause the poor charging rate? It shows virtually no charge on LOW, and only about 7 amps on HIGH charge. Am I overlooking something? I attached a direct ground from the ground side of the field resistor on the switch to insure a good ground, and did the field to ground bypass test, which would slightly increase the charge rate when the switch is on L and makes no difference when the switch is on H... which I suspect is exactly how it should be. I'm gonna put the battery on the trickle charger tonight and see what the morning brings.

Today's Featured Article - A Lifetime of David Brown - by Samuel Kennedy. I was born in 1950 and reared on my family�s 100 acre farm. It was a fairly typical Northern Ireland farm where the main enterprise was dairying but some pigs, poultry and sheep were also kept. Potatoes were grown for sale and oats were grown to be used for cattle and horse feeding. Up to about 1958 the dairy cows were fed hay with some turnips and after that grass silage was the main winter feed. That same year was the last in which flax was grown on the farm. Flax provided the fibre which w ... [Read Article]
