Voltage drop at HEI in "crank"

[Dead Parrot]

I never saw a mention of it being hard to start, just an interest in voltage drop. IS the thing having starting problems?

My suggestions on order of things to replace if needed:
1. Battery cables. Old but nice looking cables can be rotted on the inside.
2. Have the battery tested. It may be good.
3. Have the alternator tested. Low battery issues can be due to lack of good charge.
4. Only if needed, replace battery. No point in spending $100+ if not needed.
