negative corrosion
From day one I have had issues with the starter on this 74-74. I replaced the starter with a new High torgue unit. The starter clutch gear. The solenoid, the starter relay, the battery and all the wires as well. When the bike sits for a week without starting, in a garage with the temp of no lower than 45 deg F. (its winter time up here but heated) it will hardly roll. Sounds like a dying cow. I keep it on a tender 24-7 and yet it still does that. Hot of course it will turn a little better cuz the oil isn't thick when warm but is still really laboured. What I have noticed however is that there seems to be a lot of corrosion accumulating on the negative cable. I can and must assume it makes for a bad connecting as well. I clean it off and I really don't see any difference though. I have the starter grounded to the frame, shout I ground it to the negative battery as well. This really has me stymied. I have replaced everything. What is wrong. The starter was a new "all ***** " starter that has a lot of torque and cost me almost $400 Canadian. The wires I purchased pre made from an local HD dealer. They are stock, should I look there for something larger? HELP

Is the new battery big enough for the starter? Heavy duty starters can require a larger CCA battery than stock...that starter also suggests using 4 gauge cables.

Cajun, what's the CCA rating on the H12 battery (thinking it is only around 240 though). All ***** recommends using a battery with a minimum of 300 CCAs for their starter units.

Panz, this is what I have - interstate ihd-12 28Ah conventional cycle-tron battery and according to what I can find it has 240 cca. So that is to low for an "all *****" high torque starter? Can someone here recommend one that I should be using. Im up here in Canada so a lot of the things you guys get in the US we don't. Give me a couple reccomendations if you can. Thanks a bunch

herz a source that carries a replacement one (Scorpion hYIX28L) and looks like a direct replacement for the HD12 as far as size and connections and delivers 380CCA which would give you a couple more than the minimum recommended CCA. I have ordered from them before and have not had a problem. Hopefully someone else will chime in as well. My last battery for the 84 was ordered from Jireh but all I needed was the standard replacement because my 84 is stock except for +30 on the cylinders and the 32amp charging system. Last discussion I had heard about Jireh was that the standard replacement batteries were on back order and I have not seen a high amp battery offered by them.

And to answer your question..All ***** posts that their minimum recommended battery is a 300 CCA unit, so I would assume that the 240 just isn't getting the job done.

Ok, I bought a new Interstate AGM battery with 310 cca. Ill put it on tonight and see what happens. I sure hope this works the way everyone says it will. I don't want to ruin that brand new starter cranking it over slow and labored.

Well it spins a tad better and I mean a tad. All the electrical components of the starter system are brand spanking new. Starter, cables, solenoid, starter relay, Starter Clutch gear and a 310 cca AGM battery. Grounded all over the place as well. Im not happy.
The bike has 8.5:1 pistons instead of stock but I know that aint it cuz it will drag before the first roll sometimes. other times spins like a bitc&. I have built four different Harleys and have never had something this silly rear its head. And when im talking sillieness, three were ironhead sportsters, one 1975/w electric start, one 1968 kicker/w a magneto and one 1965 kicker with a special electronic distributor. This is my first shovel. I thought they were so much simpler to figure out over the old sporties.

Check the voltage while cranking the bike...if it drops below 9 volts...either the battery is bad...you have a bad connection...or the cables are not big enough. Bad connection includes the solenoid...even though it is "new" it is hard to find a quality one these days.
If the voltage is good, do you have the thrust washer (number 14) in place? If it is missing the starter can bind and will not turn over...I have seen bikes require 2 thrust washers not to bind.
If that is good check out the shifter lever (number 7)...if it is bent or worn it can also cause the starter to bind.
